3、ical balance of growth and human health, and restrict the sustainable economic and social development. Therefore, environmental tester is very important for our daily lives.The design of the environmental test instrument

4、 is made of four basic modules from the following: the host control module, optical detection and analog-digital conversion module, temperature measurement module, voice broadcast module, LCD module. It can be summarized

5、 of the principal AT89S52 microcontroller as the core, with the temperature measurement, the light sensor monitoring module to measure the ambient temperature and light conditions, and using the ISD1730 to broadcast the

6、monitoring of the temperature and light conditions, at the same time, the detected temperature values and the luminance values will be displayed in the LCD. Through programming, it will achieve kinds of functions such as

7、 analog-digital conversion, temperature and light monitoring and other voice broadcast. Design completed environmental testing to be completed for the following functions: 1. Strength under a light warm Tip: If the light

8、 weak, the voice broadcast “l(fā)ight too weak to eye protection“; if strong light, the voice broadcast “l(fā)ight too, the need to protect the eyes.“ 2. Button temperature measurement, and broadcast the current temperature - “t

9、emperature, XX degrees Celsius“.According to the detected results, the accuracy of temperature display is 0.1 ℃, and the illumination light intensity values can also be divided into three levels: weak light, soft light,
