[Precise Rainfall Measurement] The Zigbee wireless rain sensor absorbs and measures water in accordance with soil conditions, accurately measuring rainfall and automatically adjusting the irrigation system to help conserve water. [Rain Sensor Adjustment Setting] Once the preset rainfall threshold is reached, the sprinkler system will automatically suspend operation. Adjust the setting by rotating the top of the rain sensor; effective adjustment range is 5mm–20mm. [Intelligent Linkage] Compatible with Zigbee time-controlled irrigation systems and requires use with a Zigbee BT gateway for connectivity. [Cyclic Timing Irrigation] In dry conditions, the Zigbee wireless rain sensor and remote controller operate according to the programmed schedule. During rainfall, the sensor detects precipitation and automatically disables the controller (even if manually turned on). After heavy rain, the system resumes based on soil moisture levels to ensure precise irrigation timing. [High-Quality Spraying Nozzle] Constructed using an indentation process for enhanced durability. Features full encapsulation for improved sealing. Utilizes wrap-around plastic technology for seamless fusion, large aperture design, high water flow, and efficient atomization. Includes a sealing gasket with a copper connector and aluminum-plastic tube to isolate metals, prevent oxidation between aluminum and copper, and extend service life. [Bendable Design] Wide-angle spray nozzle delivers a fine mist. Adjustable left and right rotation controls flow rate. The 360° flexible design can be bent and shaped freely to target specific watering areas, suitable for multiple应用场景 to meet diverse watering needs.
