Utilizing the Zigbee 3.0 protocol, it offers a more stable connection and lower power consumption, seamlessly integrating with the Tuya Smart ecosystem for easy smart home automation Can be placed on the ground for water leak detection (suitable for kitchens, bathrooms, basements, pipes, etc.); or mounted on the wall for rainwater detection (suitable for balconies, courtyards, windowsills, etc.) Equipped with 82 high-density sensing electrodes, the detection accuracy reaches 0.05mL - equivalent to the amount of a single drop of water. Compared to ordinary sensors (which require 0.25~0.5mL to trigger), the sensitivity is increased tenfold Using a high-elastic waterproof sealing ring, the entire device reaches IP67 protection level, resisting heavy rain and effectively preventing dust from entering, allowing the device to work stably in harsh environments Offline reminder: If the sensor is abnormally disconnected, you will be notified immediately to prevent missed alarms. Low Battery Alert: Automatic push notification when the battery is low, ensuring timely replacement Specifications: Product Name: Zigbee Rainwater and Water Leak Sensor Working Voltage: DC 3V Standby Power Consumption: 10~15 microamperes (µA) Protection Rating: IP67 (Completely dustproof/Strong waterproof) Wireless Technology: TUYA Zigbee 3.0 Product Model: SJ100 Transmission Power Consumption: ≈80 milliamperes (mA) Communication Distance: 10~30 meters (in an unobstructed environment) APP: TUYA/Smart Life Color: As Shown Material: plastic Package Contents: 1*Zigbee Rainwater Water Leak Sensor Only the above package content, other products are not included.
