ITEM NAME:Automatic Watering Irrigation Module Water Pump DIY Set Soil Moisture Detection Product Description Description: Automatic Watering Irrigation Module Water Pump DIY Set Soil Moisture Detection Intelligent Watering Pumping Feature: About each part of the test: 1. Test the relay module: connect the relay module VCC to 5V, connect GND to ground, connect IN to GND, the relay jumps, and when IN is suspended, the relay recovers, so you can repeatedly hear the "card" sound of the relay; 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 indicator is always on, and the green (blue Color) The color indicator light flashes once; the fork probe is inserted directly into the water, and the green (blue) indicator light is on; 3.
