5V Raindrop Controller Module with Relay Humidity Anhydrous Switch
Connected to the power supply, power indicator light, no water droplets on the induction board, the relay pull, start the relevant equipment, switch indicator light, dripping a drop of water, the relay is off, the switch indicator light does not shine
The sensor uses high-quality FR-04 double-sided material, and nickel-plated surface, with anti-oxidation, conductivity, and life more superior performance;
The module directly with high-power relay, direct control of the load;
With the potentiometer to adjust the sensitivity, control in different water, the control relay on.
