XH-M214 Automatic Irrigation Control with Hygrometer Sensor
The XH-M214 automatic irrigation control device has easy configurations for the user to have an automated irrigation system, since the user can define the ideal humidity limits for their system and consequently the system will activate or deactivate a valve.
The device and valve are functional at 12V.
Note: The valve can be found here.

How does the XH-M214 humidity sensor work?
This device has three buttons to configure our device (SET, +/button and -/button)
The configurations are:
F0 (to enter this mode just press SET)
Humidity configuration
the values that will be displayed are percentages, that is, we will set if we want 50% or 80% humidity and start turning on the valve; since if it is not at this humidity percentage the valve will be activated.
F1 (to enter this mode press SET and +/button)
Time period
once the irrigation has stopped, a percentage is placed in this section where the sensor will detect how dry the soil is; this to be able to activate the valve again.
F2 (to enter this mode press SET and +/button twice , if you want to go back press the -/button )
Calibration
we will set how accurate we require the irrigation and humidity measurement to be, they are only values between 0.1 and -1.
When the humidity is below the set value start pump, when the humidity reaches the set value to stop watering. Sensor values range from 0 to 99, dry to saturated respectively.
