Hello. I am currently working on a project, where I have to build a people counter using IR sensor. I am working on the IR sensor and have made a circuit for it. I am working backwards, due to some problems, meaning I don't have a circuit diagram for the whole sensor. Right now I have made the circuit on a breadboard as a test to check if the sensor will work. I have to create a sensor with the same components I then can solder together myself. I really need help building a circuit diagram based on these components and what I have made on the breadboard. I have attached some pictures that might be relevant.
Listed below are the components that I have used:
- IR receiver - LPT 80 A
- Infrared emitter - SFH 4841 E7800
- Voltage comparator (OPAMP) - LM111
- Digitalt trimmer potentiometer DS1804 NV
- Power MOSFET - IRL530N
- Effect Resistor på 1,5 Ohm, 1 watt
- Capacitor 470nF og 10mF
Resistors used:
3 x 10kohm
2k2 ohm
332 ohm
I really hope, that someone can help, or at least do a part of the circuit diagram. I am kinda stucked.
Thank you!
Best regards meetoo25
