Read Temperature on an ESP32 using the HTU21D-sensor
The HTU21D is a popular and affordable sensor for measuring both temperature and humidity with a microcontroller. While there are many libraries for interacting with the sensor in the arduino-ecosystem, at the time of writing this, I didn’t find a good library to support the sensor with ESP-IDF while utilizing FreeRTOS. So here is a little write-up about how I implemented a small custom driver for the HTU21D. First things first: The specification....
