APPLICATION NOTES:-

1. Test the relay module, connections :
VCC = 5V,
GND = ground,
IN = GND,
When the relay jumps and IN suspends, the relay recovers so you can hear the relay "card" sound repeatedly;

2. Test the soil moisture sensor module:
Connect the fork probe and the transmitter module with two DuPont wires, the transmitter module VCC is connected to 5V, GND is grounded, the red power light is always on as soon as it is powered on, and the green (blue) color indicator The light flashes weakly once; insert the fork probe directly into the water, and the green (blue) indicator light is on;

3. Connect the red wire of the pump to 5V and the black wire to ground. ;

4. Assemble according to the schematic diagram.

Notes:

1. This item can be soldered but you need to strip the wire, twist the copper wire together and protect it with black tape;
2. The pump cannot be run in the air for a long time;
3. The system is connected and powered on. The water pump works all the time, because the probe cannot detect the humidity in the air, so the water pump works all the time, and it installs correctly in the flower pot without any problems.
4. Water may not be poured directly tp the probe as water humidity can cause rust/broken faster.
