Product details

The Si7021 Temperature + Humidity Sensor from Adafruit is a high-precision electronics module designed for a variety of environmental sensing projects. With a relative humidity measurement accuracy of ± 3% and a temperature range of -10 to +85 °C with an accuracy of ±0.4 °C, this sensor provides reliable data for your applications. The sensor communicates via I2C, making it compatible with a wide range of microcontrollers. The module is mounted on a breakout board equipped with a 3.3V regulator and level shifting, allowing it to be operated with both 3.3V and 5V. A PTFE filter protects the sensor from contamination, ensuring long-term use. The board comes with a pin header that can be easily soldered to facilitate integration.
