The system consists of temperature sensor module, humidity sensing module and liquid crystal display module, the application of temperature and humidity sensor works by monitoring the implementation of the current environment, regularly collected data to the microcontroller, microcontroller based temperature and humidity sensor for processing the data collected, and then will receive the data to the LCD screen on the 12864, if more than expected to set the upper and lower limits, the use of diode analog alarm, due to a combination of production and fine, making the design is intelligent, practical.
