Pressure sensor of CC2530
no vote
The design is a pressure detection system based on CC2530 single chip microcomputer. The working principle of pressure sensor circuit and weak signal sensor circuit amplifying signal are briefly introduced, Through the pressure sensor, the pressure signal of the position to be measured is converted into an electrical signal, and then the signal is amplified by an operational amplifier. The analog signal is converted into a digital signal by using the AD conversion function in the CC2530 single chip microcomputer, and the weight value is obtained by processing. Finally, the weight value is transmitted to the OLED display on another CC2530 node through the RF wireless transmission function of the single chip microcomputer.
