MAXREFDES131#: IR Presence Sensor with Grid-EYE

Summary

MAXREFDES131# is a sensing solution featuring the Panasonic AMG8833 Grid-EYE®and the Maxim 1-Wire® bus, enabled by the DS28E17. The system enables presence sensing, people counting, and gestures while tethered up to 100m along the 1-Wire bus.

The board features RJ-11 connectors and convenient mounting holes for quick evaluation and implementation.

Example source code for interfacing with MAXREFDES131# is available for both Arm®mbed™ and Arduino® platforms. This design conveniently works with MAXREFDES132#, a hardware 1-Wire shield. A demonstration GUI allows for visual feedback of up to 10 daisy-chained MAXREFDES131# 1-Wire Grid-EYE sensors.

As with all Maxim reference designs, the BOM, schematics, layout files, and fab files are all available from the Design Resources tab. In addition, boards are available for purchase.
