    Key Features

    Features:

    1 This is a summary of the soil moisture sensor can be used to detect moisture, when the soil is dry, the relay off, relay and vice
    versa. Using this sensor make an automatic watering system, so that your garden plants without people to manage.

    2 adjustable sensitivity

    3 Operating voltage 3.3V-5V

    4 relay outputs, control is more convenient.

    5 with fixed bolt hole for easy installation

    6 small plates PCB size: 3cm * 1.6cm

    7 Power LED (red) and the relay and indicator (green)

    8 using LM393 comparator chip, stable



    Small plates Interface Description (2-wire)

    1 VCC external 3.3V-5V
    External GND 2 GND



    Instructions

    1 A soil moisture module most sensitive to environmental humidity is generally used to detect soil moisture.

    2 Module in the soil moisture to reach the threshold value, the relay is in the off state, the output terminal as follows: the
    normally open and common off the normally closed and common conduction; when the soil humidity exceeds the threshold value, the
    relay the state is absorbing and status output as follows: normally open and public conduction, normally closed and public
    disconnected, the user can according to this principle to embed into their own systems. Which relay wiring parameters: AC Voltage
    Max 250V, AC current maximum 10A, maximum DC voltage 30V, DC current up to 10A
