Alerton's Wireless Temperature and Humidity Sensor integrates seamlessly with the AZW-5000 wireless system to make temperature and humidity data available to a wide range of VisualLogic controllers. It is part of a fully programmable building automation system that does not require opening walls to run wires. There are two models of the Wireless Temperature and Humidity Sensor: one with a temperature setpoint knob and manual override [WTS-1050-H], and one without setpoint or override [WTS-1000-H].
