The build is based around an ESP32 microcontroller, combined with a BMP180 sensor for measuring barometric pressure, and a DHT22 sensor for measuring temperature and humidity. By taking these ...
The I2C (“Wire”) library has also gotten the ESP32 treatment, and worked just as it should with an LM75 temperature sensor ... I pulled a DHT22 sensor out of the eBay bin, and cloned Adafruit ...
