Product Code: MIKROE-4299

The Smoke 2 Click Board? is a compact add-on board containing the smoke detector's most efficient version. This board features the ADPD188BI, a complete photometric system for smoke detection using optical dual-wavelength technology from Analog Devices. The module combines the dual photodetector with two separate LEDs, and a mixed-signal photometric front-end ASIC, housed in a package that prevents light from going directly from the LED to the photodiode without first entering the smoke detection chamber. It supports an SPI and I2C serial interface, although only one is allowed at any given time in the actual application.
