TMAS Tunnel illuminance sensors provide analog measurement in Foot-candles. TMAS sensors may be mounted to monitor ambient light near each entrance tunnel portal in unidirectional traffic bores or be located in a compromise location when both traffic directions share the same bore. The TMAS sensor mounting location is selected from several factors; unidirectional or bidirectional traffic flow, dominant traffic direction, time of year requiring most contrast lighting and maintainability.
