About this item
The surface is treated with nickel plating, which has a widened sensing area, which can improve the electrical conductivity, prevent the problem of easy rust in contact with soil, and extend the service life.
The product can control the humidity of the soil in a wide range, and the corresponding threshold value can be adjusted through the potentiometer.
