Automatic Irrigation Module DIY Kit

Product Information:

Someone asked if the sensor supports the measurement of soil moisture value. Popularize the knowledge through technology. Humidity value refers to the quality of water contained in one cubic meter of air for air. However, this indicator cannot be measured in the soil due to the uneven dissolution of water in the soil, and has no discussion value. This board can roughly measure the humidity and decide the switch of watering equipment according to the humidity. The sensitivity can be roughly adjusted with a potentiometer. Stable quality, trustworthy!

Kit Includes:

● Relay module - 1 piece

● Soil moisture probe+comparison module - 1 piece

● Small water pump - 1

● 4 No. 5 battery boxes -- 1

● USB power cord - 1

● Silicone hose --- 50cm

● DuPont Line - 10

Tests On Each Part:

1. Test relay module: connect relay module VCC to 5V, connect GND to ground, connect IN to GND, the relay will jump, and if IN is suspended, the relay will recover. In this way, you can hear the relay "jamming" repeatedly;

2. Test the soil moisture sensor module: connect the fork probe and the transmitter module with two DuPont wires. Connect the VCC of the transmitter module to 5V and GND to ground. The red power light is always on when the power is on, and the green (blue) indicator light flashes faintly once; Insert the fork probe directly into the water, and the green (blue) indicator is on;

3. Connect the red wire of the water pump to 5V and the black wire to ground. The water pump works. Pay attention to the test for 1s. Do not work in the air for a long time;

4. Assemble according to the schematic diagram.

Be Careful:

1. This product can be welded free, but you need to peel the wire, twist the copper wire together, and protect it with black tape;

2. The water pump shall not operate in the air for a long time;

3. The system is well connected, powered on, and the water pump works all the time. It's right. Because the probe cannot reach the humidity in the air, the water pump works all the time. If it is correctly installed in the flowerpot, there will be no problem.

This product does not need programming, nor does it include SCM, so please do not force the buyer to provide code. This baby does not provide power supply, you can use a charging bank (5V DC) as the power supply, or use 4 No. 5 battery boxes and install 4 batteries for power supply

1. The relay module and sensor are connected to the power supply and ground;

2 The water pump line is connected to the negative pole of the power supply, and the red line is connected to the relay;

3 The sensor is connected to the input port of the relay;

4 Sensor connected to soil detector
