Specification Brand : KeeYees BulletPoint1 : 【Surface using Nickel-Plated】The KeeYees soil moisture module,the surface using nickel-plated treatment,widened sensor area,can improve the electrical conductivity, to prevent Sensor is easy to rust. BulletPoint2 : 【Adjustable soil moisture】You can control the set value of soil moisture by adjusting the potentiometer on the module. Clockwise adjustment will increase the humidity and the counterclockwise will be smaller. When the humidity is lower than the set value, DO outputs a high level. When the humidity is higher than the set value, DO outputs a low level. BulletPoint3 : 【Stable Performance】The KeeYees soil moisture sensor module iuses the LM393 chip and include dual mode output mode. More accurate with analog output. BulletPoint4 : 【More Extensions Functions】The KeeYees soil moisture sensor module is not only accurately detects the humidity of the land, but also has more extension functions: automatic watering the vegetable garden, garden, control the flower pot soil moisture ect. BulletPoint5 : One gallon of concentrate is dispensed in 3 to 5 minutes depending on the flow rate.
