Highly sensitive Rain sensor module + Relay Control Module

for Arduino robot kit

Specification

Product Use:

Arduino robot kit, raindrops, rain, plant leaf wetness sensors, can be used for the monitoring of a variety of weather conditions, and directly

with relay output to control the motor start-up and shut down.

Introduce:

1, the sensor uses high quality FR-04 double-sided materials, King Size 5.0 * 4.0cm, and with a nickel-plated surface, has superior performance

against oxidation, electrical conductivity, and life;

2, Module directly with high-power relay, direct control of the load;

3, Distribution bit sensitivity adjustment control moisture control relay open.

Features:

Connected to the power supply, power indicator light, sensor board that there are no drops of water, the relay does not operate, switch light off,

drop a drop of water, the relay, start the related equipment, light switch,

Wipe at the water droplets, and restored to the original state.
