FS157L Wireless Water Sensor

Application: The FS157L is designed so that the transmitter is mounted on the wall and the flood sensor is placed in a location where water presence, such as a result of leakage or flooding, is probable. Upon flood detection, a digital message is transmitted, composed of the detector' s ID code and sensor number followed by various status and other messages. Alarm and other data are thus forwarded to the alarm system. Features: 1. Designed the water sensor for easy installation on the ground. 2. Used to detect the presence of water at any desired location. 3. With CPU to control code hopping versions, no need for DIP switches for ID code. 4. Low standby current on sleep mode to save power. 5. Built-in tamper switch and zone switch to set-up sensor zone. 6. LED indicates signal transmission and battery condition. 7. High transmission power is for long distance working area. 8. The sensor has low battery detector function which can report to console.
