This reference design provides a low BOM cost smoke detector design that passes UL217 9th edition sensitivity and fire room tests. Using a modulation-based photoelectric architecture, this reference design is able to achieve high rejection of ambient light for application in chambered or chamberless smoke detection. This design also has a high signal-to-noise ratio for the signal chain that helps to enable robust algorithms for reduced false alarms in smoke detector applications and particulate sensing in air quality sensing applications. This design uses the low-power modes of the MSPM0L1306 microcontroller to achieve 10 years of battery life from a 9V alkaline battery.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
