Sonoff  Temperature and Humidity Sensor :

• A digital sensor that measures temperature and humidity and outputs a calibrated digital signal.
• To guarantee that the sensor has very high reliability and outstanding long-term stability, it uses temperature and humidity sensing technology in addition to specialized digital module acquisition technology.
• A high-performance 8-bit MCU is connected to an integrated single-chip temperature and humidity sensor chip in the sensor.
• The Si7021 sensor is a cost-effective and high-quality sensor with ultra-fast reaction time and anti-interference capabilities.
• The 2.5mm 4-pole stereo audio male plug connector on the sensor is ideal for use with the Sonoff TH10/TH16.
