Abstract

The invention discloses an intermittent smoke detection alarm device based on ESP8266. The detection alarm device comprises a casing, in which a smoke sensor, a low-power-consumption operational amplifier, a buzzer alarm and an ESP8266 module are arranged. The smoke detection alarm device relates to the technical field of detection alarm systems. One path of the smoke sensor analog quantity is connected to a comparator, and when the concentration exceeds the set threshold value, the buzzer alarm is triggered. The other path is connected to an ADC pin of the ESP8266, and the digital quantity ofthe smoke concentration is read and saved in the built-in Flash files. The digital quantity exceeds the set threshold value, WiFi is started, and the alarm information is notified to users through the Internet of Things platform. The ESP8266 module sends the historical data of smoke concentration to the platform at regular time for users to check at any time. Most of the time of the ESP8266 module is in a deep sleep mode to reduce the power consumption, and only the alarm clock is timed to the comparator, a deep sleep mode is triggered to exit and enter a working mode. The device adopts a MicroPython firmware and Python code, the functions of smoke detection and interaction communication with the platform are realized, the code is concise and the reliability is high.

Description

technical field [0001] The invention relates to an intermittent smoke detection and alarm device capable of being connected to the Internet, which belongs to the technical field of computers. technical background [0002] With the continuous progress of the society and the rapid development of the economy, the pace of urbanization is advancing by leaps and bounds, and various facilities in cities and towns are becoming more and more perfect. The high-rise buildings that can be seen everywhere are daunting. However, people are always most concerned about safety issues. Now, whether it is an ordinary family building or a commercial high-rise residence, fire and other safety hazards not only bring huge economic losses, but also bring lingering trauma to people's hearts. Due to the large number of floors and dense population, once an emergency fire is sent out, it will be difficult to evacuate and even more difficult to remedy, which will inevitably cause serious casualties and ...
