So far, so good. Using the MOCREO temperature sensor, you can easily monitor the temperature changes in the plant room and track the history record. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. I have an Arduino Yun which primarily uses 5V, so that could be why the previous sensors died so quickly. It uses I2C for data transfer so it works with a wide range of microcontrollers. Add a new variable "ledStatus" that can be either "ON" or "OFF". Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. DHT22 is one of the most common IOT temperature and humidity sensors, it can measure temperature between -40C and80C (1C) and humidity from 0% to 100% (1%). This sensor has a typical accuracy of +- 2% relative humidity, and +-0.3 C. I was having issues reading the DHT22 sensor on a Raspberry Pi 4B.
