Connect your ESP8266 to any available Wi-Fi network

 1.jpg

The ESP8266 is a microcontroller developed by Espressif  Systems. Known as a WiFi Module, this microcontroller has the ability to perform WiFi related activities like Internet of things applications and home automation. Ranging in price and features, there are many types of ESP8266 modules available, but all of them are incredibly useful for IoT world.

Regardless of the IoT application you’ve developed, when using the ESP8266, you must set the WiFi credentials into the ESP8266’s firmware to establish the required connections and be able to send data to the cloud. This is one way to connect, but you can also build your own access point into the board making an universal firmware which will establish a connection in any network available just by pressing a button.

Controlling Industrial Flow Using IIoT Connected Devices

Industrial process control has long been associated with legacy systems in the shop floor. As Internet technologies continue to advance, bringing increased security and connectivity, manufacturers have begin to turn to connected devices to bring their industrial processes online.

This video, made by our friends at VERSE Technology, shows a practical example of how a Liquid Injection process can be controlled remotely from the Internet.

Build a Tank Volume Reader for Under $30 using ESP32

The Internet of Things has brought a lot of formerly complex device applications into the homes of many craft brewers and wine makers. Applications with level sensors have been used for decades in large refineries, water treatment plants, and chemical plants. With sensor prices falling, now both industrial and DIY can monitor the volume of any tank, barrel, or canister.

The sensors available on the open market can sense most anything and are classified accordingly. Sensor used for measuring humidity are termed humidity sensor, pressure called pressure sensor, distance are called position sensors, and so on. In a similar fashion, the sensor used for measurement of fluid levels is called a level sensor.

Build a People Counter for $30 Using an ESP8266 and NodeMCU

A people counter is a device used to measure the number of bodies traversing an entrance, hallway, street corner, etc. If you need to know how many people exist in a space – this is your simple solution. Typically used in retail stores, large events,, and smart office buildings, this counting technology has provide insights to both the number of bodies in an environment and how they are behaving in said environment.

Build your own smart baby monitor with Intel & Ubidots

There are lots of wearables in the market nowadays. We found it interesting to see one for babies being built within the maker community. The materials needed to make the monitor are affordable, and it’s a great tool for parents who might want to check more parameters about their babies than the ones provided by a webcam.

SONOFF Tutorial: A Wi-Fi Room Temperature Controller for $10


sonoff_th-7.png

In our last blog post we learned how to use the SONOFF Smart Switch to control a relay from Ubidots. In this case, we’ll learn how to control an Air Conditioner with the SONOFF TH, a variation of the original one that includes temperature and humidity sensors. Using these readings, we’ll use Ubidots’ Event engine to turn on or off your air conditioner automatically, depending on the room temperature.

SONOFF Tutorial: A Wi-Fi Smart Switch for $5

In this guide you will learn how to control any 110-240V appliance for $5, using Itead’s SONOFF device. Compared with the $30 WiFi smart plugs out there, the SONOFF is a great alternative for making smart home and even industrial IoT projects at a larger scale. Moreover, it is based on the popular ESP8266 Wi-Fi chip, making it compatible with the Arduino environment and other resources like our ESP libraries at Ubidots.

WiDo IoT Node Review

We recently got a support ticket about the WiDo board from DF Robot. As it was the first request for this module, we immediately ordered a unit to get our hands on it.

After some minutes of playing with the board, we were positively impressed. Its Arduino form factor makes programming a breeze, and the fact that it integrates a WiFi module makes it very attractive for most IoT projects (no need for a WiFi shield).
