Maxim’s reference design, the MAXREFDES131#, is a sensing solution featuring the Panasonic AMG8833 Grid-EYE and the Maxim 1-Wire bus, enabled by the DS28E17. This system enables presence sensing, people counting, and gestures while tethered up to 100 m along the 1-Wire bus. The board features RJ-11 connectors and convenient mounting holes for quick evaluation and implementation.

Example source code for MAXREFDES131# is available for both Arm® mbed™ and Arduino® platforms. The 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.

The MAXREFDES130# is an Arduino® form factor shield compatible with ARM mbed and Arduino platforms.  It provides a complete reference for prototyping your next building automation design. This reference design includes eight 0 V_DC to 10 V_DC analog outputs, one 4 mA to 20 mA output, one 4 mA to 20 mA input, eight non-latching relays, three latching relays, an RTC, and 1-Wire master. The MAXREFDES130# works well with one or more of the MAXREFDES131#, the 1-Wire, Grid-EYE sensor, to make a complete building automation solution.
