[ZigBee soil monitoring sensor] Remotely monitor soil temperature and humidity. You don't need to be on site frequently to detect the current soil state and moisture content in real time, with fast response speed and accurate measurement. [Voice control] The soil monitoring sensor has voice control function, and can detect the current soil moisture in real time through Alexa/Google Home voice control. [Multi-mode calibration, adjustable sampling time] Supports multiple calibration methods for temperature, air humidity and soil humidity, with more accurate data, and the sampling time range is 0 to 1004 seconds (1 minute 44 seconds). After insertion, you can quickly detect the ambient humidity. [Intelligent water shortage alarm, real-time data monitoring] Track temperature, humidity value and soil humidity changes around the clock to grasp the planting environment in real time. After setting the parameters, the device can intelligently detect the moisture content and issue an alarm in time when there is a lack of water. [Intelligent linkage] Can be linked with the intelligent water valve to achieve automatic irrigation.
