Abstract

In order to solve the problem of low resolution of three-electrode electrochemical sensor and high cost of optical detection instrument

electrochemical sensor monitoring system with STM32 as the core is designed

and the volume fraction of NO

in the atmosphere is measured with low cost and high resolution electrochemical sensor technology. Experiments show that the sensor response time T90 is severely affected by temperature at-10～ 10 ℃ . Sensor sensitivity temperature characteristic curve S（T） = 0. 197 60 + 0. 002 13 T-0. 001 21 T2（-10 ℃

40 ℃）

correlation coefficient R2 is as high as 0. 991 7

the system detection limit is about 1. 5 ×10-9（3σ） with a time resolution of 10 s. The accuracy of the experimental system is verified and compared with the reference device LP-DOAS system

the two obtained good agreement. The linear fitting slope is 1. 159 ± 0. 005

and the correlation R2 is 0. 901. Experimental results show that this technology provides a low-cost way to accurately measure NO

in the ambient atmosphere.
