This application report describes how to implement an ultra-low-power
photo-diode-based smoke detector using the MSP430F2012 and an external
operational amplifier that is powered from two AAA batteries. The complete schematic
is shown, and the solution is discussed. The complete code is downloadable from
www.ti.com. In addition, a solution for a piezzo-electric buzzer driver is shown that
produces >85-dB sound pressure level at a 10-foot distance.
