Mh Sensor Series Flying Fish Ir Sensor Datasheet Fixed (Exclusive Deal)

Here are the verified specifications. Ignore any PDF that claims different voltages or pinouts without looking at the back of the board.

Your object is too shiny or too dark. This sensor hates glossy white surfaces (reflects too well) and pure black surfaces (absorbs all IR). For line following, use white tape on black paper. Mh Sensor Series Flying Fish Ir Sensor Datasheet Fixed

You don't need a "fixed" datasheet; you just needed the correct one. The MH Flying Fish is a TCRT5000 reflective sensor paired with an LM393 comparator. Treat it as a digital switch that triggers when something gets within 2cm. Here are the verified specifications

Your potentiometer is mis-set. Turn the blue box trimmer counter-clockwise. The Flying Fish has a digital output, not analog. The pot adjusts the threshold . If the threshold is too low, it will always read "1" (nothing detected). This sensor hates glossy white surfaces (reflects too

Decoding the MH Flying Fish IR Sensor: Why Your Datasheet is Broken (And How to Fix It)

Today, we are going to fix that. Here is the actual working datasheet for the MH Flying Fish IR Sensor—no confusion included.

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.
