NETVOX Wireless Water Sensor R718WA is an alarm device for 2-way leak 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
