Relay noise
Functionality is fine but the relay click is quite loud if mounted indoors.

Good sensitivity
Works well but you need to adjust the potentiometer carefully to avoid false triggers.

5 FAQ
Q: Is this compatible with 3.3V logic?
A: Yes, the module operates comfortably between 3.3V and 5V DC.
Q: How long does the sensor panel last outdoors?
A: The nickel coating is durable, but we recommend shielding it from direct UV exposure for longevity.
Q: Can I connect a 12V pump directly to the relay?
A: Yes, the relay supports up to 10A, which is sufficient for most 12V water pumps.
Q: Does it detect mist or only heavy rain?
A: You can adjust sensitivity via the potentiometer to detect light mist or heavy rain.
Q: Are connection wires included in the box?
A: Yes, we include a set of Dupont jumper wires for easy connectivity.
