Features: This product requires no programming and does not contain a microcontroller. Therefore, we do not provide any code. We do not supply electricity About testing: 1. Test the relay module: connect VCC of the relay module to 5V, GND to ground and IN to GND. The relay will emit a pulse. When IN is empty, the relay will be restored so you can hear the sound "Kaka". 2. Test the soil moisture sensor module: connect the fork probe and transmitter module with two dupont wires, connect the VCC transmitter module to 5V and GND to the ground. The red power indicator is always on as soon as the device is turned on and the green (blue) light is on once; Immerse the fork probe directly into the water. The green (blue) light will light up. 3. Connect the red wire of the pump to 5V, the black wire to the ground, the water pump starts to work. Please note: the test can be carried out for 1 second. Because it cannot be exposed to air for a long time. 4, according to the assembly diagram. Note: 1. This product does not need to be soldered, it requires wire stripping, copper wire twisting and black tape protection. 2, the pump can not work in the air for a long time; 3. Plug in the system and turn it on. The pump works all the time. That's right, because in the air the probe cannot detect moisture. If you install it in the flower pot, it can work normally. Note: Do not pour water directly onto the soil probe. If the water humidity is too high, the product will rust and stop working.
