NETVOX Wireless Water Sensor R718WA is an alarm device for water leakage detection. When the water sensor detects a leak, it will send an alarm message to the gateway. When the water sensor detects that there is no water leak again, it will send a back to normal status message to the gateway, which uses the SX1276 wireless communication
module.
Example Applications.
- Engine room
- Warehouse
- Smart home
- Archives
- Air conditioning
- Semiconductor plant
- Data centre
