SHT20 I2C Temperature & Humidity Sensor (Waterproof Probe)

Introduction This SHT20 I2C temperature & humidity sensor is equipped with waterproof probe. It comes with the 4C CMOSens® SHT20 temperature & humidity sensor chip and the probe has gone through dual waterproof protection test.
The SHT20 I2C temperature & humidity sensor adopt Sensirion techniques. Except the humidity sensor of capacitive type and the temperature sensor of band gap , SHT20 contains an amplifier, A/D converter, OTP memory and a digital processing unit. Compared with early SHT1x series and SHT7x series, SHT20 shows a strong reliability and long-term stability. It can measure surrounding environment temperature and relative air humidity precisely.
There is also a built-in 10k Pull-up resistor and 0.1uf filter capacitor. It enables the sensor to be directly used with the microcontroller such as Arduino. We recommend DFRobot Gravity 4Pin Sensor Adapter convenient.

Projects Project 1. Smart Compost Bin Monitoring System -Based on 4G IoT and SHT20

Introduction:

The other day my friend asked me to help him remake his compost bin, he wants a device that allows him to remotely get the real-time temperature and humidity inside. So I add some electronic parts on it.
