Temperature & Humidity Sensing Using Arduino Uno and DHT 11 Sensor Author : Sohel Datta The project involves utilizing an Arduino microcontroller and a DHT11 sensor to measure and display real-time ...

An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...

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 ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...
