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.

Turn a fan on when the temperature is too high! – Electric Imp Tutorial

In our last Electric Imp tutorial we learned how to measure temperature, humidity and overall thermal comfort with Ubidots. This time we are going to make a simple on-off fan control. We will log the temperature to Ubidots and trigger an event when it is over 30ºC, so that the Electric Imp turns on a fan, and then a trigger to turn it off when temperature is below 27ºC.

It really works like a charm, so here we go:

Logging Temperature, Humidity, and Dew Point with Electric Imp

The Electric Imp is an amazing device for IoT projects and its integration with Ubidots makes it very simple to create graphs and SMS/Email alerts in a few minutes. This Electric Imp tutorial we’ll teach you how use the Electric Imp breakout board with a DHT11 sensor to measure temperature and relative humidity, and then compute the Dew Point using Ubidots’ math engine.
