Software:

PSoC Designer 4.1


The PSoC is configured to listen to a condenser microphone through two stages of PGA gain, a BPF2 and a comparator (in that order), to provide an activity-detection scheme based on audio. Audible warnings and an alarm are sounded after an entrance and exit delay, to convince any unwanted visitors to vacate the premises.
