摘要
Abstract
QM-N5 air-sensitive sensor is used in mines to check the gaseous concentration in mines. The information in the mine is collected by QM-N5 air-sensitive sensors and converted into digital signals by 555 timer; the random disturbance in the signal is re-moved by the temperature and humidity compensation circuit; the display and alarm are performed.A scheme of detecting the gaseous concentration in mines is proposed.The project is concise and reliable, and can detect the gaseous concentration in mines.关键词
