Information

Grove - PIR Motion Sensor
[47068]

CHF 10.50

This device claims to operate at between 3 and 5 volts.
The device I have is very unstable if powered at 3.3 volts, triggering spuriously say on a very small voltage drops, for example when a LED , powered from the same power supply, lights.
I've tried a small resistor in series with the device and large capacitor across the power input and that has not helped.
However, at 5 volts, it functions perfectly.
