【Good Quality】The surface is treated with nickel plating, which can improve the conductivity, prevent the problem of easy rusting in contact with soil, and extend the service life.
【How to adjust】Dual output mode, digital output, and more accurate simulation output. The blue potential in the module is used to regulate soil humidity. If you adjust it clockwise, the controlled humidity will increase and it will be smaller against the clockwise.
【Control the humidity of the soil】Control the corresponding threshold by adjusting the potentiometer. When the humidity is lower than the set value, the start relay is activated, and when the humidity is higher than the set value, the relay is disconnected.
【Wide range humidity 】If the humidity is lower than the set value, the DO will output a high level, and if the humidity is higher than the set value, the DO will output high levels and DO is low.
【Widely Application】It can be used in the module plant watering device equipment without managing your garden plant. This must have a tool to connect the garden! We recommend that you wet the indoor plant to water or monitor the soil in the garden.
