12V Raindrop Control Relay Module Leaf Humidity Waterless On Switch Automatic Control Sensor ModuleItem NO.: 12V Raindrop Control

Raindrop Controller Relay Module

Product Use:

Arduno robot kit, rain drop, rain, plant leaf humidity sensor, can be used for monitoring various weather conditions, and with relay direct output to control motor startup and shutdown.

Product Introduction:

1. The sensor is made of high-quality FR-04 double-sided material, with an oversize area of 5.0 * 4.0CM, and the surface is treated with nickel plating, which has superior performance in terms of oxidation resistance, conductivity and service life;

2. The module is directly equipped with high-power relay to directly control the load;

3. The potentiometer adjusts the sensitivity to control the opening of the relay when the water content is different.

Function Introduction:

When the power supply is connected, the power indicator light is on. When there is no water drop on the sensing board, the relay is closed, and the related equipment is started. The switch indicator light is on. When a drop of water is dripped, the relay is disconnected, and the switch indicator light is not on,

Performance Parameters:

Module power supply: 12V static current: 5-12mA

Load capacity of relay: 250V 10A (AC) 30V 10A (DC)

Delivery List:

1. One raindrop sensing board and one control board

2. 2 20cm DuPont cables for easy connection

Connection Method Of Open Circuit:

The function of the above connection method is that when the relay is not pulled in, the common end and the normally closed end are connected, which is equivalent to the switch being disconnected and the control equipment not working without power. When the relay is pulled in, the common end and the normally open end are connected, which is equivalent to the switch being connected and the equipment working with power.

Connection Method Of Normally Closed End Circuit:

The function of the above connection method is that when the relay is not pulled in, the common end and the normally closed end are connected, which is equivalent to the switch being closed and the circuit being connected, the control equipment will work with electricity. When the relay is pulled in, it is equivalent to the switch being disconnected and the circuit not working without electricity.
