12V soil moisture sensor controller module for automatic watering
When the humidity is lower than the set humidity, the start of the humidity means that when the soil humidity is lower than the set humidity, the relay will automatically pull in, start the spray, and the water pump will do the humidification action, and it will automatically stop when the set humidity is reached.
usage:
The soil humidity control threshold can be adjusted by the potentiometer, which can automatically control the vegetable garden, automatic watering of the garden, the control of the soil humidity of the family flowerpot, various electronic games, etc., with a high-power relay, which can control high-current equipment, which is less than the set humidity Automatically start the relay to close, automatically alternate when the humidity is greater than the set humidity, and have a delay function to solve the problem of non-delayed humidity critical state relays flickering. It is a simple and practical soil humidity control system.
product description:
1. The surface is treated with nickel plating, which has a widened sensing area, which can improve the conductivity, prevent the problem of easy corrosion in contact with the soil, and prolong the service life;
2. The product can control the humidity of the soil in a wide range, and adjust the corresponding threshold through the potentiometer. When the humidity is lower than the set value, the relay will be activated, and when the humidity is higher than the set value, the relay will be disconnected;
3. The product has a delay function with an interval of 3-5 seconds. When the humidity is detected in a critical state, the relay will not flicker, and stroboscopic phenomenon will appear;
4. The product adopts Songle high-quality relays, which can withstand a load of 1500W and meet the requirements of most people;
5. The product has power indication and relay pull-in indication.
Product parameters:
Power supply voltage: 12VDC input current: more than 100ma
Load: 250V 10A AC or 30V 10A DC (currents below this range can be used)
Module instructions:
1. The sensor is suitable for soil moisture detection;
2. The blue potentiometer in the module is used to adjust the threshold of soil humidity. It is adjusted clockwise, and the controlled humidity will be greater and counterclockwise;
3. Because this module has a delay function, when adjusting the humidity value, you need to wait about 5-8 seconds for each adjustment, and see the change of the relay. The green LED light also changes accordingly until it is adjusted to meet the requirements.
