AnyShake Explorer uses three velocity geophones (Z, E, N) to detect the seismic waves generated by the earthquake, the geophone is a device that converts ground movement into voltage. This solution is more sensitive than most existing homemade seismograph based on MPU6050.
AnyShake Explorer consists of ADC, MCU, and serial ports. The differential ADC is used to read the geophone voltage count. The ADC is connected to the MCU via SPI protocol. The MCU is responsible for collecting data from the ADC and sending it to AnyShake Observer via serial ports.
AnyShake Explorer is open-source and provides schematics and PCB layout that you can use directly.
See README.md in hardware directory.
See README.md in firmware directory.
Please visit anyshake.org/docs/introduction for quick start guide and more information.
The features of AnyShake Explorer are as follows:
- Differential geophone input
- 3-component geophone support
- RS232 / RS485 / TTL serial ports
- Flexible channel packet length
- Variable serial port baud rate
- Seismic data checksum verification
- Support reset from AnyShake Observer
- LED indicators for power, ADC, and serial port
AnyShake Explorer is designed and developed by @bclswl0827, test work is done by @TenkyuChimata.
Thanks to the following tools and libraries, AnyShake Explorer is made possible!
Some may ask why we didn't use Arduino IDE, the reason is that Arduino IDE is not suitable for large projects, and it is not easy to manage dependencies. PlatformIO is a cross-platform IDE that supports Arduino, and it is also a package manager for Arduino libraries. It is very suitable for large projects.
