Published:2011/3/23 1:57:00 Author:Jessie | Keyword: Temperature/frequency, Audio decoding, temperature control | From:SeekIC

Circuit as shown, it is composed by many harmonic oscillator, audio decoder, relay control cooling equipment, twitter sound circuit andAC step-down rectifier circuit, etc. IC1 is a 555 time-based integrated circuit. It composes a self-motivating much harmonic oscillatorwith thermistor RT, R1, C1. When environment temperature changes, RT resistance of negative temperature coefficient (NTC)is changed too.
