Overview
The TSL1401 Linear CCD Camera Module uses a 128-pixel linear CCD (128 Ć 1) to convert a scanned scene into an electrical signal. The collected gray-value data is output as an analog voltage on the AO pin and can be sampled by a microcontroller A/D converter for robot car visual line tracking, path recognition, tracking, obstacle avoidance, and other image-processing tasks. The module is designed for fast response and is less affected by ambient light, supporting indoor and outdoor high-speed tracking use.

Details

The TSL1401 module converts a single line of 128 pixels into an analog gray-value output for fast line tracking.

Designed for MCU projects, the analog AO output can be sampled by an ADC for tracking and simple vision tasks.

A 1D line scan reduces processing load compared with full-frame cameras while still capturing edge and line contrast.

Linear scanning helps achieve higher-speed tracking by sampling only the line data needed for navigation.

Less data per frame means simpler firmware and quicker response on typical microcontrollers.

For applications where ambient light varies, the linear CCD approach can provide more consistent line information than IR sensing.

Example wiring with an STM32 board for acquiring AO output and driving the SI/CLK timing signals.


An optional bracket allows flexible mounting height and pitch angle when tuning detection distance and field of view.

Common use case: robot car visual line tracking for path recognition and obstacle-avoidance logic.



Mechanical drawings provide mounting hole locations and overall dimensions for enclosure and chassis design.


Pinout: GND and VCC power the module, AO outputs analog gray value, and SI/CLK control acquisition timing.



Package includes the module and 5-pin cabling for quick connection to a controller or test setup.

The TSL1401 linear CCD camera module comes with a height/angle adjustable bracket plus a wire harness and XH2.54 5-pin double-ended cable for straightforward wiring.
