Research on open-pit mine monitoring system based on single-chip microcontroller combined with temperature and humidity sensors
To meet the real-time monitoring requirements for temperature and humidity in open-pit mines,a com-posite film for temperature and humidity sensors was prepared using polyimide film as raw material,and a tempera-ture sensor and a humidity sensor were prepared based on the film.Combined with the AVR microcontroller and the designed temperature and humidity sensor,the open-pit mine monitoring system was designed and realized.The ex-perimental results showed that the designed temperature sensor had good linearity and sensitivity,with a maximum nonlinear error of 2.5%,a correlation factor of 0.998,a sensitivity of 0.002 0℃,and an average response time of 50 seconds.The designed humidity sensor had good linearity and sensitivity,and the response time was fast,with an average response time of 40 seconds,meeting the design requirements.The designed open-pit mine monitoring sys-tem can achieve remote temperature and humidity monitoring in open-pit mines,with the characteristics of fast re-sponse speed,small size,and low power consumption.
