Temperature and humidity monitoring alarm system based on MCU
[Abstract] Temperature and humidity are the two factors which are now the first taken into account in Industry and Agriculture, Meanwhile, temperature and humidity Monitoring alarm system has already been one of the popular modern studying fields. It is urgent to discover a monitoring alarming system that has such merits as low costs, easy to use and accurate. The design is a system, which uses STC89C52 Microcontroller to make real-time monitoring for temps and humidity, achieving the function of temps and humidity over-limit alarming. The design uses the way of modularization and layering based on STC89C52 Microcontroller, taking advantage of the novel temp-humidity sensor, DHT11, mainly reaching the goal of the detection to them. Then collect the signal detected by the sensor, converting to digital signal. Furthermore, exploit the Microcontroller to analyze and tackle the data, providing signal to the monitor. In the aspect of graphic, we will use LCD1602 monitor to display the measured temps and humidity data. For alarming, it will make use of LED , taking light-and- sound alarming when the temp or humidity exceeds.
