I assume you are using a Mayfly v1.1 board and not an older v1.0, because it had a hard time providing a stable 12v for that particular type of sensor. But are you using the onboard 12v source by selecting 12v on the Grove voltage selector jumper, or are you using one of the new screw terminal boards that has its own 12v boost circuit on it? And have you put a voltmeter on the power wires going to the sensor when it’s on to verify that it’s receiving 12volts?
