The design of [dzzie]’s smart humidor consists of an Arduino, WiFi shield, LCD + button shield, and most importantly, a DHT22 temperature and humidity sensor.

Here are the steps I took to install Node-RED on my Raspberry Pi B, and then to wire it up to a DHT22 humidity and temperature sensor to log the conditions in my office. It’s based on my work last ...

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 ...
