Re: IR Distance Sensor
Hi, u can try the SHARP GP2D12/GP2D15, but this is for the distance from 10cm to 80cm. But I tried the couping before using "GaAIAs Infrared Emitter SFH 487" with "NPN-Silizium-Fototransistor SFH 309" or "Silicon NPN Phototransistor SFH 309 FA". It can give u the distance between 10cm. u can try this too "TOSHIBA LED Lamp GaAℓAs Red−light Emitter TLRA270". But I had tried out, using either one of the transmitter with same receiver, no problem at all. U just need to defind your range with the voltage received in your data acquisition stage.
