TMA-296
The TMA-296 Doppler sensor is a multifunction model, equipped with two relay outputs. It is designed for detecting vehicles at intersections, as well as for speed warning or smart lighting applications. The minimum and maximum speed, the distance of detection and the direction of the movement are adjustable conditions to activate the relays.
Compact and lightweight, it can be installed quickly, without civil engineering works or traffic stops.

Use cases
- Traffic lights:
- call and/or phase extension
- coordination of hubs
- green wave
- green bonus
- sanction red
- Lighting of outdoor parking lots (stations) on vehicle movement detection
- Activation of signals and alerts:
- “approaching vehicles” for cyclists
- “dangerous turns” powered by solar energy, only when a vehicle approaches in order to achieve substantial energy savings
- “ghost driver”
