SHT20 Temperature and Humidity Sensor

Measure Air Temperature and Humidity

  • -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 voltage range
  • Light-use and Weatherproof versions available

What it is

The light-use SHT20 sensor comes in a plastic enclosure with a 1m length of cable. The Weatherproof version is housed in a sintered metal enclosure to provide weather resistance.

The board uses the Qwiic Connect System, an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins. Adafruit calls these connectors STEMMA QT.

Using it

There is 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 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.
