How long can the temperature humidity sensor battery last?
The temperature and humidity sensor is powered by 2*AAA batteries. This kind of battery is very easy to buy in the supermarket, and street stores. With 2 AAA batteries, with low power consumption technology, the sensor can work for 1 year. It has a low battery remind function, when the battery voltage is lower than 2.5V±0.1V, it will send a push message to remind customers to change the battery on time.
