Good value kit
Easy to configure the sensitivity potentiometer. Relay clicks loudly but functions well for my small pump.

Reliable detection
No false positives so far. The corrosion resistant probe is a huge plus for long term soil contact.

Perfect for automation
Works flawlessly with my Arduino setup. The capacitive sensor is much more durable than resistive ones.

Solid component
Instructions could be more detailed, but there are plenty of tutorials online. Works as expected.
Q: What is the maximum water pump size supported?
A: The relay supports up to 10A. Please check your pump's current draw to ensure it stays within this limit.
Q: Is the probe completely waterproof?
A: The probe is designed for soil insertion and water exposure, but the connector junction should be kept dry.
Q: How do I calibrate the sensitivity?
A: Use the small potentiometer on the board. Turn it while the probe is in dry soil until the LED switches state.
Q: Does this come with a power adapter?
A: No, the kit includes the sensor and relay module only. You will need to supply your own power source.
Q: Can this module operate on 3.3V logic?
A: The module power input requires 5V or 12V, but the signal output is compatible with 3.3V microcontrollers.
