Hot selling spot 12V soil moisture sensor controller module automatic watering starts when the humidity drops below

Brief description

The working state of this module is 12V power supply. When the humidity is lower than the set humidity, the relay will be in the suction and connection mode,

When the humidity is higher than the set humidity, the relay will automatically close and start the dehumidifier, ventilation and other equipment. When the humidity reaches the set humidity, it will automatically stop.

When the humidity is lower than the set humidity, the relay will automatically close and start the humidification action of spraying, water pump, etc. when the soil humidity is lower than the set humidity. When the set humidity is reached, it will automatically stop.

Purpose

By adjusting the soil moisture control threshold through a potentiometer, it can automatically water vegetable gardens and gardens, control soil moisture in household flower pots, various electronic competitions, etc. It is equipped with a high-power relay that can control high current devices. When the humidity is lower than the set humidity, the relay will automatically start and close, and when it is higher than the set humidity, it will automatically disconnect. It also has a delay function to solve the problem of the relay flashing continuously in the humidity critical state without delay. It is a simple and practical soil moisture control system.

Product Introduction

1. We use high-quality soil sensors produced by our company for soil moisture detection. The surface is treated with nickel plating, which widens the sensing area and improves conductivity, preventing rusting when in contact with soil and extending its service life;

2. The product can control the humidity of the soil in a wide range. The corresponding threshold can be adjusted through a potentiometer. When the humidity is below the set value, the relay will be activated and closed. When it is above the set value, the relay will be disconnected;

3. The product has a delay function, which can delay for 3-5 seconds. When the humidity is detected to be in a critical state, the relay will not flash and a flicker phenomenon will occur;

4. The product adopts high-quality relays from Songle, which can withstand a load of 1500W and meet the requirements of most people;

5. The product has power indication and relay engagement indication;

Electrical parameters:

Supply voltage: 12VDC Input current: greater than 100ma

Load: 250V 10A AC or 30V 10A DC (currents below this range can be used)​

Module usage instructions

1. The sensor is suitable for detecting soil moisture;

The blue potentiometer in the module is used to adjust the threshold of soil moisture. Clockwise adjustment will control a higher humidity, while counterclockwise adjustment will control a lower humidity;

3. Due to the delay function of this module, when adjusting the humidity value, it is necessary to wait for about 5-8 seconds each time, observe the changes in the relay, and the green LED light will also change accordingly until it is adjusted to meet the requirements.

4. Please refer to the image below for the wiring method of the product.
