Hi , i have a project of " Fire Fighting Robot " :roll:

and i'm having a problem in the proximity sensor that i want to use many IR sensors instead of using ultasonic ( very expensive ) but the maze area will be affected by :
- The light level of the surrounding in the testing area
- The room will be lit by overhead high pressure sodium vapour lights.

so how can i overcome the effect of these things

​

Thanks in advance.
 

So you must use an IR filter passing only the light from your IR source. In addition you should modulate YOUR IR light (a chopper) and use a selective amplifier after the photodetector, to avoid unwanted response.
