Description
The Sonoff Si7021 is a freestanding indoor temperature and humidity sensor, with a 0.5-metre cable that makes it easy to position. It measures relative humidity in a range of 0 to 100% and temperature between -10 and 85 °C, covering the needs of a home or small office. It operates on a 3.6 V battery and supports extreme storage from -65 to 150 °C, although its intended use is domestic. It is a practical option for monitoring the environment of a room and acting accordingly, without relying on the mains power supply.
