Digital Temperature & Humidity Sensor - HTU31-D - STEMMA QT / Qwiic - Adafruit 4832

Digitalsensor manufactured by Adafruit. It was equipped with theHTU31-D system- the third generation of TE sensors fortemperatureandhumidity measurement. The temperature measurement range is-40 ° C to 85 ° C(with an accuracy of +/- 0.3 ° C), and the humidity isfrom 0% to 80% RH(with an accuracy of +/- 2% RH). The module uses theI2Cinterface for communication with the main module. It was also equipped withSTEMMA QT / Qwiic connectorsand outputs in the form of solder pads. The set includes a dedicatedgoldpinstrip (2.54 mm pitch), which should be soldered in the marked places.

Temperature and humidity sensor from Adafruit.

The sensor from Adafruit can be connected in two ways - using the STEMMA QT / Qwiic connector or through the standard goldpin connectors. The set includes a 1x8 strip with a pitch of 2.54 mm, which must be soldered to the marked solder pads. Connect the sensor according to the following dependencies:

• VIN - power pin in the range from 3 V to 5 V
• GND - the ground of the system
• SCL - clock line of the I2C communication interface
• SDA - clock line of the I2C communication interface
• SRT - RESET pin
• ADDR - pin for selecting the address of the I2C communication interface
