In the music player based on the 51 single chip microcomputer, the DH11 temperature and humidity sensor is used as the hardware foundation to control the music playing through collecting the surrounding temperature and humidity. The MCU needs external +5V voltage regulated power supply. When the MCU works, the initial value of the timer is set by software to get the required sound frequency. Through 8 bit common cathode digital tube, the temperature can be displayed; the signal output by the MCU can be amplified and the buzzer can be sent to sound.
