Si7021 Temperature & Humidity Sensor Breakout Board - STEMMA QT is backordered and will ship as soon as it is back in stock.

DESCRIPTION

This lovely sensor has ± 3% relative humidity measurements with a range of 0–80% RH, and ±0.4 °C temperature accuracy at a range of -10 to +85 °C. Great for all of your environmental sensing projects. It uses I2C for data transfer so it works with a wide range of microcontrollers.

To get you going fast, Adafruit has added a custom made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the LIS331s or to chain them with a wide range of other sensors and accessories using a compatible cable. They’ve also broken out all the pins to standard headers and added a voltage regulator and level shifting to allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively.

There's a PTFE filter to keep the sensor clean, that's the white flat thing on top. Also comes with some pin header. Some light soldering is required to attach the header for use in a breadboard but it's easy to do.

FEATURES
  • Dimensions: 17.8mm x 15.3mm x 3.0mm / 0.7" x 0.6" x 0.1"
  • Weight: 1.0g
