The Design of High Precision Pyroelectric Infrared Processing Circuit

Abstract:

As information technology is becoming more and more popular, infrared ray technology also has been rapidly increasing especially after A.D. 2000. Infrared ray detection and control technology has been widely applied in various domains of the national economy and people’s daily life. The paper makes analysis on the characteristics of pyroelectric infrared sensor output signal, and puts forward a high precision pyroelectric infrared acquisition circuit. This circuit has high sensitivity, high accuracy, low noise, anti-interference and other features, and it is fit for all sorts of practical detection controlling circuits.
