Product description: Temperature and humidity sensor - HDC3022 - STEMMA QT / Qwiic - Adafruit 5989
The Adafruit temperature and humidity sensor is an advanced solution for all electronics enthusiasts and professionals who need precise measurements. The use of the TI HDC302x chip makes this sensor achieve a typical accuracy of ± 0.5% for humidity measurements in the range of 0% to 100% RH and ± 0.1 ° C for temperature in the range of -40 ° C to 125 ° C. The sensor supports the I2C interface, which allows for simple communication, without the need for logical level converters. Power supply in the range of 1.62 V to 5.5 V allows for easy adaptation to various applications. The sensor is also equipped with STEMMA QT / Qwiic connectors and leads in the form of solder pads. The kit includes a dedicated goldpin strip (2.54 mm pitch), which should be soldered in the marked places.
The manufacturer has prepared a user guide that will help you get started with the sensor.
