Countries attach great importance to the development of this area. People in order to obtain information from the outside world, must be by means of sensory organs. And rely on peoples own sense organs, in the study of natural phenomena and laws, and production activities in their function is far from enough. To meet this situation, we need sensors. The use of breath alcohol tester to conduct on-site testing of drivers, so to ensure that the driver lives and property. Temperature and humidity measurement and control of production and automation in the coal mine safety monitoring plays an important role. Smoke alarm is by monitoring the concentration of smoke to achieve fire prevention functions. In this paper, the DHT11 digital temperature and humidity sensors, MQ-2alcohol concentration sensor, MQ-3smoke concentration sensor, based on single chip microcomputer control chip design STC89C52 for a temperature and humidity, alcohol concentration, smog density detection sensor alarm system, and puts forward the design of the multi-functional sensor, think it to peoples lives have great influence, require the use of single chip micro
