visualization of real-time logistics monitoring microsystem is designed based on MEMS sensors, which are high ability, low power consumption and low cost. The MEMS acceleration sensor BMA280, the MEMS pressure sensor BMP085, the display module, the memory module and the radio frequency (RF) module are integrated in the intelligent microsystem. Intelligent microsystem block diagram is shown in Fig...
This work presents an open-loop, fully differential capacitive MEMS accelerometer implemented in CMOS technology. The mathematical model of this open-loop system is derived, which considers non-ideal factors in circuits such as nonlinear distortion and noises. These non-ideal factors have been discussed through system level simulation using MATLAB. Simulation results show that the system has good...
