Design and Implementation of Laboratory Safety Monitoring System Based on AT89C51
The design uses the AT89C51 MCU as the control center,realizes the humidity and temperature da-ta acquisition through the temperature and humidity sensor DHT11;the MQ-2 gas sensor is used to detect the con-centration of harmful gases in the laboratory to prevent the leakage of CO,fire smoke and other harmful gases.At the same time,they are displayed on the LM041L real-time.When the detection data exceeds the limit,the alarm is given.The system is simulated and tested by the simulation software proteus.
