The SmartWalk TX-S is the first microwave sensor specifically designed to monitor trails for users approaching a road crossing from up to 60 feet away. Upon detection, the SmartWalk TX will activate the trail crossing warning lights increasing their effectiveness since they are only activated while trail users are present. The SmartWalk TX will reliably detect all types of trail users regardless of weather conditions.

The SmartWalk TX-S has low power requirements making it ideal for solar applications.
