This is a DIY KIT for an Automatic Watering And Irrigation System for your garden! It might help you remember to water your indoor plants or check the soil moisture in your garden. You may automatically irrigate the vegetable garden, as well as the plants and flowers, by setting the potentiometer to manage the soil humidity threshold. Particularly appropriate for frequent travelers!
Check The relay module:
connect the relay module VCC to 5V, GND to ground, into GND, and the relay will tick, and when IN is suspended, the relay will resume, so repeatedly, you can hear the relay "Kaka" sound.
Test the soil moisture sensor module: Connect the fork probe and amplifier module with two DuPont wires. The amplifier module VCC is connected to 5V, and GND is grounded. When the power is on, the red power light is always on, and the green (blue) light is flashing once. The fork probe is used. Directly inserted into the water, the green (blue) color indicator light is on.
The red line of the water pump is connected 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.
Connect the system, power on and if the pump has been working, it is correct. Because in the air, the probe can not detect the humidity, there is no problem if it is installed correctly in the pot.
