Smoke Intelligent Monitoring Terminal Data Acquisition System

Comfortable and safe living environment of human eternal pursuit of the material goals. With computer technology, communications technology, control technology rapid development, people's living conditions put forward higher requirements, want to live life in a modern, comfortable environment, security of living space. Through environmental monitoring system, users can obtain real-time information about the living environment, such as: temperature, humidity, gas concentration, fire information. And environmental information collected for other household equipment run-time parameters to achieve intelligent control of the environment. The terminal as a part of the smart home, real-time monitoring of gas concentrations and smoke density, and when the concentration exceeds the threshold value, the alarm by wireless means

Intelligent terminal through a variety of sensing circuits of the gas concentration detection chamber and smoke density information, and with the preset threshold parameter value, based on the comparison result of the intelligent terminal to issue the corresponding alarm information, and can display the current time in real time gas concentration in the indoor and smoke density values for parameters such information, and through WIFI, GPRS and other wireless communications in a timely manner all kinds of monitoring information to the tenants
