2AIT9-PG-H02Water Leak Sensor

Water Leak Sensor User Manual The water leak sensor adopts sensitive detection technology and sends water leakage alarms to the host in time via wireless 433.92MHz signals. It is widely used in homes, computer rooms, warehouses and other places to effectively prevent water damage losses. Device Status Operating Voltage: DC 3V (2×1.5V AAA batteries) Alarm Indicator: Red LED Alarm Duration: >8 seconds Alarm Volume: >80dB at 1m Transmitting Frequency: 433.92MHz Wireless Range: >100m (in open air) Operating Temp.: -10°C to +55°C Operating Humidity: <95%RH (no condensation) Size: φ 67×24.5mm Waterproof Rating: IP66 Power on Please read this manual carefully before use and keep it properly for future reference. Remove the insulating sheet: Pull out the insulating sheet vertically. Status test Press the button. The sensor will beep after 1 second, indicating it's working properly. If there's no beep, open the back cover with a screwdriver and replace the battery. I.Product Overview 1.1 Product Appearance II.Technical Specifications III. Using the Water Leak Sensor Indicator Probe Probe AAA battery Buzzer Test Button Water detection and alarm If you drip water on the sensor probe or place it on a wet surface, the sensor will alarm. Drip water Water leakage Wipe clean Alarm cancellation: Take the device out of water and dry it to stop the alarm. Press the button Indicator Light (Red) Buzzer Test alarm Water leak alarm Low battery alarm Flashes once Flashes continuously 3 slow beeps "Beep--" Flashes continuously 15 slow beeps "Beep--" Flashes 3 times 3 quick beeps "Beep Beep Beep" "Beep" once PG-H02R After the device alarms, shake it quickly several times to remove moisture from the buzzer's sound holes. Then wipe the top and bottom probes with a dry soft cloth or tissue, and put it back in place. Warning: The device should work at a temperature between -10°C and 55°C, and humidity below 95% RH. Do not disassemble it by force, otherwise the device may be damaged. Environmental Protection: Don't throw used batteries with household waste. Put them in the provided recycling bin. VI.Maintenance VII.Troubleshooting When the battery is low, the device will emit three fast beeps, and the red LED will flash quickly three times. The mobile app will also send a low-battery reminder to prompt you to replace the battery. How to replace the battery: Take off the bottom cover and open the battery compartment. Take out the old battery and insert two new AAA batteries of the same type. Close the battery compartment and test if the sensor works properly. IV. Installing the Water Leak Sensor V.Battery Replacement Installation method: Effective distance verification: After successfully adding the device, at the selected water leak sensor installation location, press the TEST/SET key once. If the host receives an alarm message, it indicates that the sensor and the host can communicate effectively. Way: Place it directly on the plane to be monitored. AAA battery ProblemCauseSolution No response when pressing test button The device does not sound when there is a water leak. False alarm Triggered by water/metal Touching probe with wet hands, water spills (e.g., handwashing, esp. in bathroom), high humidity, or metal connecting probes cause alarms. Device is waterproof.
