Great for DIY projects
Used this with an Arduino setup. The logic levels are consistent and the relay clicks loudly enough to know it's engaging.

Perfect for my rooftop tank
Installed this last week and it works flawlessly. The pump turns on exactly when needed and shuts off when full. Very happy with the purchase.

Probes could be better quality
The controller board is fine, but the sensor wires feel a bit thin. Might replace them with stainless steel probes later.

Good value but wiring needs care
The module itself is solid. Just make sure you follow the diagram closely for the relay connections. Works well otherwise.

Saves so much water
No more overflow issues. The automatic shut-off is reliable. Highly recommend for home reservoirs.
Q: What is the maximum pump power supported?
A: The relay supports up to 10A, so please check your pump's current draw before connecting directly.
Q: Does this come with the sensor probes?
A: Yes, the kit includes standard water level sensor probes with 2-meter cables.
Q: Can I use this with a 24V power supply?
A: No, this module is designed strictly for 5V or 12V DC input. Using 24V may damage the circuit.
Q: Is the circuit board waterproof?
