That’s an Arduino wired up to a DHT22 temperature and humidity sensor ($9.95 from The Robot Shop). Using the wiring diagram helpfully provided by Adafruit I connected the DHT22 to the Arduino, with ...

Now the DATA pin of GPIO serves as digital in for Ameba. DHT sends data: DHT sends out the temperature/humidity data (which has size 5 bytes) in a bit by bit manner. To represent each bit, DHT first ...

If you want to make your own system for doing so, Instructables user ICStation shows off how to use an Arduino to do it. The system here monitors temperature, humidity, and smoke levels and alerts ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will ...
