Product overview:
The intelligent cushion sensor can not only recognize whether someone is sitting on the cushion, but also correctly recognize whether there is a person or only other objects on the cushion. When no one is on the cushion or only other objects are placed, the sensor outputs a high level of 3.3V, and when someone sits on the cushion, it outputs a low level of 0V.
Tip: This smart seat sensor has no temperature measurement function by default.
