Smoke Detector with Ultra Low Power MCU
Texas Instruments
This reference design describes the implementation of a low-cost smoke detector, including discrete amplification circuitry into the MSP430 ADC for smoke detection in the chamber. The design also includes an audio buzzer and LED feedback.
Features
- Passive Infrared (PIR) Smoke Chamber With Discrete Amplification Circuitry to ADC Input
- Alarm Buzzer and LED Feedback
- Low Power (2.07 µA) and Small Code Size ( < 1KB Flash)
- One Timer and Multiple GPIOs Free for Proprietary Communications
- This reference design is tested and includes firmware, hardware design files, and a getting started guide with instructions for integrating other PIR smoke chambers.
