Description :
Netvox water leak sensor R311W is a LoRaWAN device compatible with LoRaWAN protocol (ClassA). When the Z311W sensor detects the leak, it will send an alarm message to the gateway. When the sensor detects no leaks, it will send a message that shows no leak to the gateway.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance, anti-interference ability and so on.
LoRaWAN: LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers.
- Use ultra low power consumption LoRa wireless network technology, battery life is longer, detector and sensor fission design.
- Effectively prevent the effects of high humidity environment on the product.
- High accuracy and sensitivity, good long-term stability, reliability, etc.
- This product can be widely used in the basement, hotel room, water tower, pool, swimming pool etc detection of water level, leaking.

Hi, how do you set the AppEUI and AppKey for these devices? Are they fixed to your AppEUI? If so, which LoRaWAN Networks are compatible?
A: Hello Mr. Ben Ward, Thank you for your inquiry. You can specify the AppEUI and AppKey or assigned by us as factory default. After joining network, you can also send command from network server to change the AppEUI. Thank you. Best regards, Netvox Technology Co., Ltd.
