Generic BFD-1000 Five Channel Infrared Tracking Module Tracing Sensor

The BFD-1000 module operates from 3.0V to 5.5V DC. This range makes it directly compatible with both 3.3V logic systems (like Raspberry Pi or ESP32) and standard 5V Arduino boards without requiring a logic level shifter.

The module provides digital TTL-level outputs. Each of the five tracking channels outputs a logic HIGH or LOW signal based on the surface detected. Simply connect these output pins directly to your microcontroller's digital input pins. The module also includes a dedicated pin for the integrated touch sensor input.

Yes, the front-mounted infrared distance sensor features an adjustable detection range. You can modify its sensitivity, typically via a potentiometer on the module, to set the effective detection distance between 0 and approximately 5 cm to suit your specific application.

The module is designed for black/white line detection at short ranges, typically from 0.5 mm up to 40 mm (4 cm) from the sensor surface. It is pre-configured for high sensitivity and generally does not require calibration for standard use, though ambient light conditions can affect performance.
