Sensors

The reflectance sensors measure the speed of the wheels that travel on top of the metal track. The sensors measure wheel speed by detecting infrared pulses reflected off the reflective tape on the wheels. the infrared light is emitted by a small LED diode mounted above the sensor.

The reflectance sensors are an important part of the AEV as they give accurate measurements on the current wheel speed. These accurate measurements allow the team to design and implement complex coding which allow the AEV to run independently of manual controls once the program has been initiated.

Reflectance sensors are complex tools but are very useful for determining the speed of the AEV, which ensures that the AEV can be operated safely at all times.
