XH-M214 12V Digital Soil Humidity Sensor Controller Irrigation System Automatic Watering Detector Module Soil Moisture Test Probe Description: The probe can be inserted directly into the soil. It is a digital display of soil moisture. When the humidity is lower than the set value, start the pump to start watering, and stop watering when the humidity reaches the set value. The operation is very simple. It is intelligent and humane.   Specification: Item: Soil moisture controller module Model: XH-M214 Power supply voltage: DC 12V Output mode: output switch Humidity range: 20-99% RH Control accuracy: 1% RH Control current: 10A Net weight: 30g Size: 52*43*16mm   Use Tips: Please follow the wiring diagram in the instructions. You can choose the appropriate wiring method according to the load voltage you use 1. F0 set the starting humidity (the humidity at which the solenoid valve or pump starts to work), press the "SET" key to display "F0", press the "SET" key to display the start humidity, and press the +/ key to display the "SET" humidity value 2. F1 set the stop humidity (the humidity at which the solenoid valve or pump stops working) press the +/- key to switch to "F1", press the "SET" key to display the stop humidity value, press the +/ key to set the humidity value 3. F2 humidity correction There is no correction error for normal use. Numerical correction when multiple modules are used at the same time is conducive to unified management and operation. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x Soil Humidity Sensor
