The Mobeye CM4300 WaterGuard is an effective tool for leak monitoring and alerting. If the leak sensor detects water-based fluids, the WaterGuard responds with an alarm message (push message/SMS/call/email) to the configured alarm recipients via its integrated 4G LTE-M communication module. The device is battery operated, which means that this compact product will operate autonomously for over 12 months. A 12 - 24 V DC or AC power source can be connected as an option to monitor the availability of the power supply. The additional two NO/NC inputs are used to connect external sensors (e.g. float sensor) or devices. This allows even more monitoring, such as overflows, water tanks, the operation of heaters, ventilation systems or various other electrical machines. https://elecena.pl/product/19068778/10393-water-sensor-with-leak-sensor-gsm 2021-07-14 https://elecena.pl/product/19068778/10393-water-sensor-with-leak-sensor-gsm 2022-07-03
