["Description:\r\nThe probe can be inserted directly into the soil. It is a digital display of soil moisture. When the humidity is below the set value starting pump starts watering, when humidity reaches the set value to stop watering. The operation is very simple. It is intelligent humanization.\r\n\r\nParameters:\r\nProduct name:Soil Moisture Controller Module\r\nModel: XH - M214\r\nPower supply voltage: for DC 12 V\r\nOutput way: Output switch\r\nHumidity range: 20-99% RH\r\nControl precision: 1% RH\r\nControl current: 10 A\r\nNet weight: About 28 g\r\nSize: 52 * 43 * 16 mm\r\n\r\nUsing attention:\r\nPlease follow the wiring diagram of the description. You can choose the appropriate wiring mode according to the load voltage you use\r\n1>. F0 setting start humidity(the humidity of the solenoid for valve or the pump start working)\r\nPress the “SET” button to display “F0” and press the “SET” button to display the start humidity, and press +/ button to “SET” the humidity value\r\n2>. F1 setting stop humidity (the humidity of the solenoid for valve or the pump stops working)\r\nPress +/- button to switch to “F1”, press the “SET” button to display the stop humidity value, and press +/ button to SET the humidity value\r\n3>. F2 humidity correction\r\nNormal use without correction error.The correction of values in the use of multiple modules at the same for time is conducive to a unified management operation.\r\n\r\nNote:\r\nItem color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.\r\nPlease allow 1-3mm slight deviation due to manual measurement. Thank you! \r\n\r\nPackage include:\r\n1pc Digital Humidity Controller"]
