1, specific description

STC89C52 microcontroller to paper, as the control, to achieve the detection of temperature, humidity, light intensity is detected, the LCD displays in real time the hardware circuit design of the circuit and real-time monitoring of the phone. In particular by temperature and humidity sensors as DHT11, photoresistors and AD0809 chip, GTM900-B wireless communication module, the ambient temperature, collect humidity, light intensity of the three parameters, storage, display and other functions, and can transmit the corresponding data in real time to the mobile phone, the system is reliable, simple, cost-effective.
