We developed the ARC-8 for the makers who refuse to settle for jittery sensor data. By focusing on signal quality, high sample rate and a compact footprint, we've created a sensor that feels like a natural extension of your code, allowing your robot to "see" the track with total confidence and zero lag.
The ARC-8 is a versatile, 8 channel analog-based IR array compatible with any microcontroller in your stack. Adorned with colorful LED indicators, it let's you dominate with style.
Featuring 8 individual reflective SMD IR modules and adequate passive filters for noise, ARC-8 comes well documented with code libraries and examples to kickstart your build.
Whether you are building a competitive line follower, maze solver or an Autonomous Guided Vehicle, its high-frequency response time makes it the gold standard for optical sensing. It’s built to scale from beginner builds to pro-level robotics with ease.

HOW IT WORKS
& PROCESSING
◘ The ARC-8 is an 8 channel IR sensor array compatible with most microcontrollers. It consists of eight independent infrared transmitter-receiver pairs that provide analog voltage outputs. Each channel detects reflected IR light from a surface, producing different output levels for dark and light surfaces.
◘ During operation, the microcontroller samples all eight analog outputs using its built-in Analog to Digital Converter (ADC). The ADC converts the continuous voltage signals into discrete digital values. These raw digital readings are then calibrated using stored minimum and maximum reference values to perform scaling (normalization), improving measurement accuracy and compensating for environmental variations.
◘ The normalized digital data from all eight channels is processed collectively. Thresholding techniques may be applied through firmware to determine active sensing regions and a weighted average algorithm is used to compute the precise position of the detected contrast relative to the sensor array. This enables continuous positional estimation instead of simple binary (0/1) detection.
◘ If the detected signal weakens or no channel crosses the defined threshold, the system can flag loss of line condition. The last known positional data can be retained for correction logic.
◘ What's to learn? : Signal Processing, Analog Electronics, signal to noise ratios. Response Optimization, Autonomous Logic using multi-channel inputs.
