Measure pH, ORP, EC or salinity with an Arduino or Raspberry Pi

SHT20 Temperature and Humidity Sensor

  • -40 to 125 C(-40 to 257 F) temperature range
  • 0 to 100 % RH humidity range
  • ±0.5% C temperature accuracy
  • ±5% RH humidity accuracy
  • I2C interface
  • 2.1 - 3.6 V voltage range

What it is

An SHT20 sensor in a plastic enclosure with a 1m length of cable.

The device uses the Qwiic Connect System for wiring, it's an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins.

Using it

There is plenty of documentation on the specification, and setup of the sensor.

The Arduino IDE, PlatformIO, and library is in their respective library managers. Any Arduino compatible board will work.

A python and rust library is available for the Raspberry Pi.

Arduino C++

Buying it

The sensor comes with a Qwiic connector to allow it to connect to any μFire board. The only thing to remember is that it is not 5V tolerant.
