| Abstract: | The CO detection system is composed of CO sensor circuit, MAX1452 analog sensor signal processor circuit and the PWM generator circuit,which is based on the MSP430F2101 MCU. It can detect concentration of 50 PPM of the toxic gas at the room temperature. The system makes use of voltage which the amplitude is 1V and the cycle is 30s, which can avoid interference of H2. Because of highly integrated analog sensor signal processor, the system is high precision. Otherwise, this system is low cost and highextensible. |
