Automatic Irrigation with Capacitive Soil Moisture Kit

About each part of the test:
1. Test the relay module: connect the VCC relay module to 5V, GND to the ground, IN to GND, the relay jumps, and when IN is suspended, the relay recovers, so that you can hear the sound of the "Kaka" relay several times.
2. Test the soil moisture sensor module: connect the fork probe and the transmitter module with two DuPont lines, the VCC transmitter module is connected to 5V, GND is grounded, just after powering, the red power indicator light is always on, green (blue) color indication The lamp flashes slightly once; The fork probe is directly inserted into the water and the green (blue) color indicator.
3. Connect the red line of the pump to 5V, the black line is grounded, the pump works, pay attention to the test for 1 second, and it is not allowed to work in the air for a long time;

Note:
1. This baby may be free of welding, but you must peel off the wire, twist the copper wire together and protect it with black adhesive tape.
2. The pump cannot work in the air for a long time.
3. The system is connected, under voltage, the pump worked, it's correct, because in the air, the probe cannot detect humidity, so the pump worked, there is no problem in the correct installation in the pot.

Note that water should not be poured directly on the probe. Many people do not know that the humidity of the water will be rusted and destroyed soon.
