Water Leak Sensor
WLS-15-NB-LTE-M


WLS-15-NB-LTE-M is a wireless water leak sensor that is designed to monitor water level and raise an alarm when high water level is detected. It is a perfect solution of monitoring water leaks in basement, garage, bathroom and kitchen or any place water leakage might occur. WLS-15-NB-LTE-M incorporates NB-IoT / LTE-M technology and can send status or alarm signals to the system server via NB-IoT / LTE-M network, providing users system deployment flexibility. WLS-15-NB-LTE-M can also connect with add-on optional extendable water probe or water sensing cables for different applications, hard-to-reach areas and increase detection area. Completely wireless, WLS-15-NB-LTE-M can be easily installed anywhere and provide you with peace of mind.
WLS-15-NB-LTE-M instantly sends an alarm signal when detecting the presence of water and generates a loud siren as well as flashes its red LED, providing effective audible and visual alerts to prompt a timely response. The reliable and robust protection the WLS-15-NB-LTE-M provides radically reduces flood risks in any home and saves the user the potentially exorbitant costs associated with water damage restoration.
