GL-P2B has a built-in high-sensitivity 3-point microelectromechanical MEMs accelerometer module. Its data acquisition part is a miniaturized version of EDAS-24GN. Both have the same design in terms of ADC, embedded system based on ARM9 chip and Linux. GL-P2B also adds two functions: network NTP timing and network power supply, making it more convenient to use. GL-P2B has functions such as automatic detection of earthquake events, intensity calculation, and automatic estimation of parameters such as τc and Pd. It can output continuous waveform data and automatically publish earthquake trigger information, intensity information, and instrument status information through the network or SMS.
