针对家庭安全事故时常常难以预测的问题，设计了一种可远程报警的安全检测系

Aiming at the problems that are often difficult to predict in family safety accidents, a safety detection system capable of remote alarming is designed. The system mainly uses the STC89C52 single-chip microcomputer as the control core, through the MQ-7 smoke sensor, human body infrared pyrolysis sensor and MQ-5 gas Sensors detect information on fire, house theft, and gas leakage. When an alarm occurs, the system uses the GSM module to remotely alarm. The test results show that the system can accurately detect the infrared rays reflected by the human body and the signals sent by the gas and smoke sensors, and can complete the remote group SMS alarm function, which has the advantages of high integration, low power consumption, high reliability and low cost. Security alarm prevention has certain practical significance.

In view of the problem struck by family safety accidents, a safety detection system that can be remotely alarmed is designed, which mainly takes STC89C52 as the control core, and uses MQ-7 smoke sensor, human infrared heat release sensor and MQ-5 gas sensor to detect fire, burglary and gas leakage information, and when there is a warning, the system achieves remote alarm through GSM module. The test results show that the system can accurately detect the infrared reflection of human body and the signal from the gas and smoke sensor, and can complete the function of remote group texting alarm, which has the advantages of high integration, low power consumption, high reliability and low cost, which is of practical significance for the protection of remote safety alarm.

Aiming at the problems that are often difficult to predict in family safety accidents, a kind of safety detection system that can alarm remotely is designed. The system is mainly based on STC89C52 single-chip microcomputer, and uses mq-7 smoke sensor, infrared heat release sensor of human body and MQ-5 gas sensor to detect the information of fire disaster, burglary and gas leakage. When there is an alarm, the system is implemented by GSM module There is a remote alarm. The test results show that the system can accurately detect the infrared reflected by human body and the signals sent by gas and smoke sensors, and can complete the remote group SMS alarm function, which has the advantages of high integration, low power consumption, high reliability and low cost, and has a certain practical significance for remote security alarm prevention.<br>
