A robust, production-ready DHT22/AM2302 sensor driver for the WCH CH32V003 RISC-V microcontroller using TIM1 PWM Input capture mode for precise pulse width measurement. Code examples are available in ...
Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...
This is an improvement on a previous implementation, and many others that use fixed thresholds for decoding. In certain circumstances the new implementation ...
You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD ...
DHT22 utilizes exclusive digital signal collecting technique and humidity sensing technology and can ouptut calibrated digital signal. Small size & low consumption & long transmission distance (20 ...
