The sensors operate in the wavelength range of 620 … 690nm (corresponds to red light in the visible electromagnetic spectrum). This means that all optical light sources in the same color range can act as potential sources of disturbance.
Possible disturbance sources that have to be eliminated / minimized:
- Other optical sensors in the same wavelength range
- Rotary lights / flashing lights / flashlights
Possible approaches to minimizing such disturbance sources:
- Separate sensor from other sensors in the same spectrum
- Shield sensors with housing / covers
