## Description

This sensor array features five downward-facing reflectance sensors for line-following or edge-detection, and it also includes front- and side-facing detectors that work together with IR emitters on the Zumo 2040 main board to create a proximity sensor system. It is primarily intended as a replacement part, but it can also be used to make your own Zumo 2040 robot if you only want a subset of the parts included with the [full kit](https://core-electronics.com.au/zumo-2040-robot-kit-no-motors.html).

**Included components**

The Zumo 2040 Front Sensor Array includes:

- 2×12 extended male header for sensor array
- two 1×3 right-angle male headers and two shorting blocks – jumpers for sensor array
- two wide-angle and two narrow-angle through-hole infrared LEDs (these plug into the main board and serve as forward emitters for the proximity sensor detectors located on the front sensor array)
