Overview
Sonoff Si7021 Temperature and Humidity Sensor is a digital temperature and humidity sensor with a calibrated digital signal output. It adopts dedicated digital module acquisition technology and temperature&humidity sensing technology to ensure that the sensor has a very high reliability and excellent long-term stability. The sensor includes an integrated single-chip temperature and humidity sensor chip, which connects to a high-performance 8-bit MCU. The Si7021 sensor has advantages such as excellent quality, ultra-fast response, anti-interference ability and cost-effective. The sensor has 2.5mm 4-pole stereo audio male plug connector, which works perfectly with Sonoff TH10/TH16.
Features
- Relative humidity and temperature measurement
- All calibrated, digital output
- Good long-term stability
- No additional parts required
- Ultra-low energy consumption
- The sensor is fully interchangeable
