Introduction of WL-410 Relay Output Function

Scarlet Wireless Wind Alarm System At a Glance

WL-410/XB Wireless Wind Alarm System consists of a wind speed sensor and a receiver. The sensor measures wind speed and transmit data to the receiver. The 3.5-inch LCD display of receiver shows readings on the main page and the history graphs are shown in different pages. Based on the preset values, the receiver can trigger local alarms such as LED lights and buzzer, or trigger external indication via 3 built-in relays when measured wind speeds exceeding the thresholds. The volume of alarm is adjustable from 85 to 90 dB. The latest model WL-410XB - which has sensor with higher, +14dB power for longer transmission (1300m). W410XB has also added Bluetooth connectivity between receiver unit and smartphone. Users can install the App to monitor wind speed on their smartphone and pair to multiple smartphones.
