Mh Sensor Series Flying Fish Ir Sensor Datasheet Fixed -

Here is the corrected, verified technical data for the MH Sensor Series Flying Fish IR sensor.

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

| Pin Number (from left) | Label on Fixed Datasheet | Wire Color Recommendation | Function | |------------------------|--------------------------|---------------------------|-----------| | 1 | VCC (5V) | Red | Power supply input (3.3V to 5V DC) | | 2 | GND | Black | Common ground | | 3 | OUT | Yellow/White | Digital output (TTL: LOW when obstacle detected, HIGH when clear) | Mh Sensor Series Flying Fish Ir Sensor Datasheet Fixed

This module is designed for digital object detection, providing a clear "Low" signal when an obstacle is within its adjustable range.

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

| Feature | MH Flying Fish (Fixed) | TCRT5000 Module | Sharp GP2Y0A21 | |---------|------------------------|------------------|----------------| | Output | Digital (LOW=obstacle) | Digital | Analog (voltage) | | Max Range | 30cm (white) | 15cm | 80cm | | Ambient Light Rejection | Poor | Moderate | Excellent | | Pinout Confusion | High (needs fixed) | Low | None (standardized) | | Price | $1.50 | $2.00 | $12.00 |

But there is one annoying problem:

You are not alone. The "Flying Fish" series (often denoted as FF or MH on the PCB) is ubiquitous in e-commerce, but reliable documentation is scarce. This article provides the for the MH Series Flying Fish IR sensor. We will cover the accurate pin configuration, voltage regulation fixes, threshold calibration, and how to modify the circuit to resolve common design flaws.
