Author: EIS Release Date: Nov 27, 2020


Analog Devices has released a reference design for a smoke alarm that meets UL 217 8th edition, along with an arduino-compatible evaluation kit.

ADI-smoke-EVAL-CN0537-ARDZ

Built around the recently released ADPD188BI optical smoke sensor, it comes with a “data package for algorithm development including more than 1,000 smoke data sets taken at UL-217 certified facilities,” according to ADI.

ADI-smoke-ADPD188BI-photoIntended for battery power, 3.8 x 5 x 0.9mm ADPD188BI includes one blue LED and an infra-red LED plus a pair of photo diodes and a smoke chamber.

Although the evaluation kit is physically compatible with Arduino, the software for the reference design that comes along with it is for ADI’s EVAL-ADICUP3029 which is built around the ADuCM3029 Arm Cortex-M3 chip and has connectors for Arduino, PMOD and Grove add-on boards.

ADI-smoke-CN0537-cct-Getting your hands on the the smoke data package requires payment, as does obtaining the algorithms that the company has written for the processor.

While the reference hardware (circuit right) is has a list price of $45, the test data will set you back $10,000 and the algorithms $50,000 – for which you get the CN0537 source code, Matlab and Pyhon algorithm development projects, documentation and 10 hours of phone support – but check this list for yourself.
