Question 1: What does a flood sensor do?
Answer: The water immersion sensor is a device that can detect water leakage and water immersion. It can monitor two states: no water to water, and water to backwater. When a water leak or water immersion occurs, the alarm information can be pushed in real time through the app, and can pass through The gateway device cooperates to control other intelligent hardware products.

Question 2: How does a flood sensor work?
Answer: The water immersion sensor uses the conductivity of water. When two probes come into contact with water at the same time, a current loop is formed. At this time, the sensor reports the state of water immersion / leakage to the gateway, which triggers an alarm or links other smart devices to perform related actions.

Question 3: What is the communication between the flood sensor and the gateway?
Answer: The flood sensor and the gateway communicate via wireless Zigbee protocol, no wiring is required. Zigbee technology is a short-range, low-power wireless communication technology. It is a communication protocol for smart home control systems that has become popular in recent years. It has the following advantages over other communication protocols: 1) ultra-low power consumption; 2 ) High security; 3) Ad hoc network can accommodate many sub-devices.

Question 4: What is the reason for the failure of the water sensor connection? How should I reconnect?
Answer: Possible reasons: 1. Operation error, please re-add the device according to the method of adding the device; 2. Too far from the gateway, move the device close to the gateway and add the device again; 3. The gateway exceeds the load of the sub-device.

Question 5: Why does the flood sensor often go offline?
Answer: Possible reasons: 1. The device is far away from the gateway. Please verify the distance between the sensor and the gateway and install the device near the gateway. 2. The battery is low or the battery is dead, please replace it with a new battery. Zigbee is installed on a metal surface and the signal is disturbed.

Question 6: Can the water sensor be used alone?
Answer: No. The flood sensor must be used in conjunction with a gateway device. The gateway device implements the conversion of Zigbee and Wi-Fi signals.

Question 7: What are the requirements for the installation of a flood sensor?
Answer: The installation of the flood sensor is simple and convenient, and it can be directly placed on the plane to be monitored.

Question 8: Does the flood sensor support dust and water resistance?
Answer: Yes. The water immersion sensor meets the international IP67 dustproof and waterproof rating standards, which can protect against short immersion.

Question 9: Where are the buttons of the flood sensor?
Answer: The keys of the water sensor are designed in the middle of the face shell. Fingers hold the upper shell and the bottom cover and press the position of the "water drop" icon to trigger the keys.

Question 10: What is the alarm level when the water level is reached?
Answer: When the detected water level reaches a height of 0.5mm, an alarm can be triggered.

Question 11: Where is the antenna of the flood sensor?
A: The Zigbee antenna of the flood sensor uses an on-board antenna, and the position of the antenna is directly above the "water drop" icon.

Question 12: What is the power supply method of the flood sensor?
Answer: The flood sensor uses CR2032 lithium metal button battery, the output voltage is 3V, and it can work for about two years under normal conditions (the actual use time depends on the specific situation).

Question 13: How is the water sensor reset?
Answer: Press and hold the reset button for 5 seconds until the blue light flashes continuously and release it to complete the reset.
