摘要
针对目前市场上气体检测设备存在检测种类单一、可调性差、适用性较低等问题,设计了一种根据实际需要,用户可自由选择检测气体种类的无线气体检测系统。该系统由MQ系列气体传感器、ADC0809、STC89C52、NRF905无线收发模块和LCD显示等构成。测试证明,当传感器检测到气体浓度超标时,实现系统自动报警。
The gas detection equipment currently available has the disadvantages of single detection type and poor adjustability and applicability.This paper designs a wireless gas detection system,in which the user can choose the detection type.The system consists of MQ Series gas sensors,ADC0809,STC89C52,NRF905 wireless transceiver module,and LCD display.Tests show that automatic warning is given when the sensor detects exceeded gas concentration.
