Model Number:
LKF-MSU204
Autonomous Sensor System
LKF-MSU204 is an autonomous sensor system. When there is an effective power supply, it will start automatically. After completing the initialization process, it starts sampling, processing and loading the calibrated sensor data into the output register, which can be accessed through the SPI port. SPI port is usually connected to compatible port of embedded processor.Table1 MSU204 Main Parameters
