Product Usage:
robot kit, raindrop, rain, plant leaf surface humidity sensor, can be used for monitoring various weather conditions, with relay direct output, control motor, etc. start and shut down.
Product description:
1. The sensor adopts high-quality FR-04 double-sided material, with a large area of 5x4cm, and is treated with nickel-plated surface, which has superior performance against oxidation, electrical conductivity and life;
2. The module is directly equipped with a large power relay to directly control the load;
3. With potentiometer to adjust the sensitivity, control the opening of the relay when different water.
Features:
Connect the power supply, the power indicator light is on, when there is no water droplet on the sensor board, the relay pulls in, the related equipment is activated, the switch indicator light is on. Drop a water drops, the relay is disconnected, and the switch indicator light is off.
