Mh Sensor Series Flying Fish Ir Sensor Datasheet Fixed Page

The onboard 10kΩ trimpot is wired as a voltage divider for the comparator's reference voltage, but the circuit uses a simple resistive divider without hysteresis.

If you have a drawer full of sensors, chances are you have a few green modules labeled MH Sensor Series "Flying Fish" . These are arguably the most common infrared (IR) proximity sensors on the market. They are cheap, reliable for line-following robots and tachometers, and they run on 5V.

Do not trust the silkscreen if it says "SIG" in the middle. On almost all Flying Fish MH sensors made after 2018, the silkscreen is incorrectly placed. Always verify with a continuity test between the center pin and the negative terminal of the power LED. The onboard 10kΩ trimpot is wired as a

Pro Tip: Some clones swap VCC and OUT. If the LED stays on permanently, swap those two wires. They are cheap, reliable for line-following robots and

The adjustment range is extremely sensitive (10% of turn changes range from 2cm to 20cm).
