1 Product function: it is used to realize intelligent irrigation of green plants, orchards and so on, and
ensure that the soil humidity of plants is maintained in the range suitable for plant growth.
（1）Real time detection of soil humidity, DWIN LCM shows the humidity value and change curve.
（2）According to the humidity suitable for plant growth, we can set the threshold value. When the
humidity is not within the threshold value, an alarm is given.
（3）According to the current season and environment, we can set the irrigation water yield.
（4）According to the set humidity threshold, the opening and closing of water pump can be
controlled in real time to realize the stability of soil humidity.
（5）Historical data can be retrieved and displayed by curve.
（6）DWIN LCM WIFI is connected to DWIN Cloud platform to obtain humidity data and display
historical curve through the APP.
