How to build an homemade IR sensors? Interfacing ...

· Typical “line following” sensors can be bought pretty cheap (<2). Eg. the QRD1114 or the QRB1134. They consist of an IR LED and a phototransistor and that’s it. When you hook them up you typically need a 220 Ohm resistor for the IR LED and a 10K pullup resistor for the signal. But you may have to play around with those resistor values to get the optimal result. You could replace the ...

Really Homemade Oximeter Sensor Arduino Project Hub

I''ve started this project playing with a KY039 heartbeat sensor that I''ve found in a kit sensor that many of us have in home. As you can see in the circuit below, it''s just a infrared led that lights a photodiode. There are also two resistors to protect the led and read the small signal of the sensor. So if you don''t have a KY039 sensor you can build your own sensor …
