    distance measuring sensor circuit diagram

    I did it but as you said 20cm or else, I have to put lens in frot of the led. could you pls tell me that where can I buy and what kind of lens it is?

    distance measuring sensor circuit diagram

    I want to measure distance not presence. We did it with ultrasonic, this is a RD project consequently we should do it with IR too. the sensors do not work like measuring the speed or else, they work measuring the lights turning angle.

    distance measuring sensor circuit diagram

    Reloadron, I didn't draw the shematic on PCAD or else, I only did it on breadboard. I will draw and send tomorrow. Vizier87, really it is a good idea, I should try it, thank you. could you please give me some information about your circuit? what kind of ir led, photodiode,op amp, timer...ect...

    distance measuring sensor circuit diagram

    Hello, I did a circuit diagram to measure distance, but this sensor can only measure 10 cm it should measure 60 cm. How can I do that? I used ne555 osilator with 40 kHz, tl084cn opamp, ir led (it must be ir led for my project) and photodiode. At the end of my circuit diagram, there is a peak...

    Infrared

    Hello, I want to ask some questions to you if you don't mind. I want to use IR sensors that can work between -5(*C) and 85 (*C) but I don't find any sensor like this. All of the product's limit is +70(*C). This sensor should sense 3cm to 30cm sensitively. I will use it in an oven...
