Automatic Irrigation Module DIY Set for Soil Moisture Detection and Automatic Water Pumping

Overview This product does not need programming not include the microcontroller so we don t provide any code We don t provide power you can use the charging treasure 5V DC as a power supply or use 4 AA batteries About Testing 1 Test the relay module connect the relay module VCC to 5V GND to the ground and IN to GND the relay is will beat if IN is vacant the relay will restored so you can hear the Kaka sound 2 Test the soil moisture sensor module connect the fork probe and transmitter module with two dupont cable connect the transmitter module VCC to 5V and GND to the ground The red power lamp is always on as soon as it is powered on and the green blue led will gleam for once put the fork probe directly into the water the green blue light will on 3 Connect the red line of the pump to 5V black wire to the ground the water pump will start work Note that the test can be performed for 1 second because it can not expose to the air for a long time 4 According to the schematic assembly Note 1 This product needn t welding but it requires you to strip the wire twist the copper wire together and protect it with black tape 2 The pump can not run a long time in the air 3 Connect the system and power the pump will work all time it is right because in the air the probe can not detect the humidity if install it to the flowerpot then it can normally work Note Do not pour water directly onto the soil probe If the humidity of the water is
