چکیده
This paper proposes a new measurement scheme of gas concentration by infrared sensor, for high accuracy measurement of gas concentration and safety protection. Furthermore, the principle of infrared absorption, test methods and optical chamber structure are expounded. And a double-beam differential detection system is designed. The paper key to introduce the software and hardware design of infrared detection system, and detail the composition of the infrared gas sensor and how to accurately measure the concentration of gas works.

متن کاملDevelopment of Micro-Heaters with Optimized Temperature Compensation Design for Gas Sensors
One of the key components of a chemical gas sensor is a MEMS micro-heater. Micro-heaters are used in both semiconductor gas sensors and NDIR gas sensors; however they each require different heat dissipation characteristics. For the semiconductor gas sensors, a uniform temperature is required over a wide area of the heater. On the other hand, for the NDIR gas sensor, the micro-heater needs high ...
