What really would compel someone khổng lồ actually develop a sản phẩm which is a complete Io
T-based home automation system? Could it be the need lớn improve the safety of your home, could it be the desire to live a Jetson-like life that millennials always dreamt of.

It is difficult lớn say, often, it is even more difficult lớn visualize the giải pháp công nghệ that is required to build a trang chủ automation platform.

Due lớn the complexity introduced by software, hardware và networking ecosystems, it becomes extremely important to learn, understand & utilize the right home automation technology for your smart trang chủ product.

We hope to lớn address some of the concerns with this article.

T home automation: Getting started

Home automation has three major parts:

Communication protocols

Each of these parts is equally important in building a truly smart home experience for your customers. Having the right hardware enables the ability to develop your Io
T prototype iteratively và respond to giải pháp công nghệ pivots with ease.

A protocol selected with the right testing and careful consideration helps your avoiding performance bottlenecks that otherwise would restrict the technology and device integration capabilities with sensors & Io
T gateways.

Another important consideration is the firmware that resides in your hardware managing your data, managing data transfer, firmware OTA updates & performing other critical operations lớn make things talk.

Applications of trang chủ automation

Rebuilding consumer expectations, home automation has been projected khổng lồ target wide array applications for the new digital consumer. Some of the areas where consumers can expect khổng lồ see home automation led Io
T-enabled connectivity are:

Lighting control
HVACLawn/Gardening management
Smart home Appliances
Improved home safety và security
Home air unique and water chất lượng monitoring
Natural Language-based voice assistants
Better Infotainment delivery
AI-driven digital experiences
Smart Switches
Smart Locks
Smart Energy Meters

The list is still not exhaustive & will evolve over the time to lớn accommodate new Io
T use cases.

Now that you are familiar with trang chủ automation applications, let’s have a detailed look at what components are involved in building a typical trang chủ automation prototype.

Home automation components

We have talked about them before, but, let’s clearly separate them into components that would finally help you build a realistic model of what major components are involved in building a smart home. The major components can be broken into:

T Sensors
T Gateways
T Protocols
T Firmware
T Cloud và Databases
T Middleware (if required)

T sensors involved in trang chủ automation are in thousands, & there are hundreds of trang chủ automation gateways as well. Most of the firmware is either written in C, Python, Node.Js, or any other programming language.

The biggest players in Io
T cloud can be divided into a platform as a service(Paa
S) and infrastructure as a service(Laa

Major Io
T platform as a service provider:

TAzure Io
IBM Bluemix

Characteristics of Io
T platforms

Again these platforms are extremely divided over the Io
T application và security-related features that they provide. A few of these platforms are mở cửa source.

Let’s have a look at what you should expect from a typical Io
T platform:

Device security & authentication
Message brokers và message queuing
Device administration
Support towards protocols lượt thích Co
AP, MQTT, HTTPData collection, visualization, & simple analysis capabilities
Integrability with other web services
Horizontal & vertical scalability
Socket APIs for real time for real-time information flow

Apart from what we mentioned above, more and more platform builders are open sourcing their libraries lớn developers. Take for example the Dallas temperature library for DS18B20 for Arduino was quickly ported because of mở cửa source development lớn a new version that helped developers lớn integrate DS18B20 with Linkit One. Understanding these things become crucial as Io
T tends to lớn evolve continuously and having an equally responsive platform makes it business safe lớn proceed.

Let’s now deeply evaluate each of these components, starting with Io
T sensors

Home Automation Sensors

There are probably thousands of such sensors out there that can be a part of this list. Since this is an introduction towards smart trang chủ technology, we will keep it brief. We will break down Io
T sensors for trang chủ automation by their sensing capabilities:

Temperature sensors
Lux sensors
Water cấp độ sensors
Air composition sensors
Video cameras for surveillance
Voice/Sound sensors
Pressure sensors
Humidity sensors
Infrared sensors
Vibrations sensors
Ultrasonic sensors

Depending upon what you need you may use one or many of these to build a truly smart trang chủ Io
T product. Let’s have a look at some of the most commonly used trang chủ automation sensors.

Temperature sensors

The market is full of them, but the famous temperature sensors are DHT11/22, DS18B20, LM35 & MSP430 series from TI. MSP430 series is more accurate than the rest but at the same time is one of the most expensive for prototyping or initial hàng hóa testing purposes. MSP430 tops all temperature sensors as the precision và battery consumption is minimum with them.

MSP430 tops all temperature sensors as the precision and battery consumption is minimum with them.

DHT11 has a very restricted temperature range và suffers from accuracy issues. DHT22, on the other hand, is a little bit more accurate but still, doesn’t make it as the preference.

DS18B20’s, on the other hand, are more accurate, as opposed to digital temperature sensors like DHT22 and 11, Dallas temperature sensors are analog & can be extremely accurate down lớn 0.5 degrees.


Take cảnh báo that often the temperatures that you directly sense from these sensors may not be very accurate and you would occasionally see 1000 F or greater values no matter what you are doing.

There’s an entire súc tích that goes around building temperature sensors, that we will address in another blog post.

Lux Sensors

Lux sensors measure the luminosity and can be used khổng lồ trigger various functions range from cross-validating movements khổng lồ turn the lights on if it becomes too dark. Some of the most popular light sensors are TSL2591 và BH1750.

Recent tests khổng lồ include TSL2591 và BH1750 into low-powered Io
T devices have found them lớn be working fairly good for most of the use cases.

Here’s a study was done by Robert and Tomas that shows how these two compare against a spectrometer & a photodiode.


To get a good idea of whether these two sensors would suffice your needs we would suggest illuminance tests followed by normalization of the data to lớn observe deviations under various situations.

Water cấp độ sensors for trang chủ Automation

While building your prototype you may consider a solid state e
Tape liquid cấp độ sensor, or lượt thích others who just use an HC-SR04 ultrasonic sensor to measure the water level sensor.

On the other hand, in other cases where those two don’t suffice, one has lớn utilize something that can deliver a much higher performance.

Float cấp độ sensors and other ICs lượt thích LM1830 offers a more precise measurement capability lớn Io
T developers. Although, they are substantially much more expensive than others.

Air composition sensors

There are a couple of specific sensors that are used by developers to lớn measure specific components in the air:

CO monitoring by Mi
CS-5525MQ-8 to measure Hydrogen gas levels
CS-2714 to measure nitrogen oxide
MQ135 khổng lồ sense hazardous gas levels (NH3, NOx, Alcohol, Benzene, smoke, CO2

Most of these are sensors have a heating time, which also means that they require a certain time before they actually start delivering accurate values.


These sensors mainly rely on their surface lớn detect gas components. When they initially start sensing, there’s always something that’s there on their surface, some sort of deposition that requires some heating khổng lồ go away.

Hence, after the surface gets heated enough true values start lớn show up.

Video cameras for surveillance & analytics

A range of webcams và cameras specific khổng lồ Hardware development kits are usually used in such scenarios. Hardware with USB ports offers khổng lồ integrate & camera module lớn build functionalities.

But, utilizing USB ports in not very efficient, especially in the case of real-time video clip transfer or any kind of clip processing.

Take Raspberry
Pi for example, it comes with a camera module (Pi cam) that connects using a flex connector directly to the board without using the USB port. This makes the Pi cam extremely efficient.

Sound detection for trang chủ Automation

Sound detection plays a vital role from monitoring babies khổng lồ turning on và off lights automatically to automatically detecting your dog’s sound at the door and opening it up for them.

Some commonly used sensors for sound detection includes SEN-12462 và Easy
VR Shield for rapid prototyping.

These sensors aren’t as good as industrial grade sensors lượt thích those from 3DSignals which can detect even ultra-low levels of noise and fine tune between various noise levels to lớn build even machine break up patterns.

Humidity sensors for home Automation

These sensors bring the capability of sensing humidity/RH levels in air for smart homes. The accuracy & sensing precision depends a lot on multiple factors including the overall sensor design và placement.

But certain sensors like DHT22 and 11 built for rapid prototyping would always perform poorly when compared to high-quality sensors lượt thích HIH6100 và Dig RH.

While building a sản phẩm to sense humidity levels, ensure that there’s no localized layer of humidity that is obscuring the actual results. Also, keep into consideration that in certain small spaces, the humidity might be too high at one kết thúc as compared lớn the others.

When you look at free and mở cửa spaces where the air components can move much freely, the distribution around the sensor can be expected to lớn be uniform and subsequently would require very less amount of corrective actions for the right calibration.

Home Automation Protocols

One of the most important parts of building a trang chủ automation product is to lớn think about protocols, protocols that your device would use to lớn communicate to lớn gateways, servers, and sensors. A few years ago, the only way to do so was by either using Bluetooth, wifi or GSM. But due lớn added expenses on cellular sim cards, & low performance of Wifi, most such solutions didn’t work.

Bluetooth survived & later evolved as bluetooth không dây Smart or công nghệ bluetooth không dây low energy. This helped bring a lot of connectivity in the “mobile server powered economy”, in this essentially your phone would act as a middleware to lớn fetch data from BLE powered sensors và sent it over to the internet.

ANT: An ultra low nguồn protocol helping developers build low-powered sensors with a mesh distribution capabilities.6lowpan

Home Automation: Which protocol is the best?

While there are some protocols that clearly offer much more than others, but it is always important lớn start from your smart trang chủ development needs & then move towards narrowing down the solutions.

The commonly preferred protocols are bluetooth không dây low energy, Z-wave, Zigbee, và Thread. The protocol selection can now be narrowed down by the following factors:

Ability to lớn perform identity verification
Quality of sensor networks
Data transfer rate
Security level
Network topology required
Density of objects around
Effective Distance lớn be covered
