Installation Precautions
The sensor should be wired correctly, otherwise it may damage the internal components of the sensor.
When the sensor is soldered to the circuit board, it needs to be soldered with a low-temperature soldering iron, and the time should not be too long, and secondly, the pins should not be squeezed by a large amount, otherwise the internal connection may be opened.
