Overview

AnyShake Explorer is a professional-grade, fully open-source seismic monitoring platform built forresearchers,engineers,educators, andenthusiasts. It combineshigh-sensitivity velocity geophones with a32-bit precision ADC to capture ultra-low-noise seismic data in real time.

Designed with versatility in mind, AnyShake Explorer transmits data viaRS-232/RS-485 serial interfaces to its companion software,AnyShake Observer, for real-time visualization, storage, and analysis. It supportssimultaneous sampling of 3-axis geophones and accelerometers, and features advanced capabilities likeGNSS/NTP time synchronization,OLED display, anddigital inclinometer.

Whether you're monitoringearthquake activity, conductingstructural health assessments, or exploringeducational experiments, AnyShake Explorer provides aflexible,hackable, andfield-ready solution that brings high-resolution seismology within everyone’s reach.

Features

  • 🧠32-bit Precision ADC – ultra-low noise data capture for professional geophones
  • 🎛️Simultaneous 3-axis geophone + 3-axis accelerometer sampling – full 6-channel motion capture
  • 🔌Multiple serial interfaces – 2× RS-232 and 1× RS-485 for flexible deployment
  • ⚙️Flexible baud & sample rates – supports up to 460,800 bps and 250 SPS
  • 📺Built-in OLED display – live status readout without a PC
  • 🧭Digital inclinometer – ensures precise leveling during installation
  • ⏱️Time sync via GNSS or NTP – millisecond-level accuracy
  • 🔒Checksum-based data integrity – reliable transmission over noisy links
  • Low power operation – only ~0.6W at 9–12V DC, perfect for remote use
  • 🖥️Cross-platform companion software – live streaming, waveform analysis, and export
  • 🛠️Fully open-source – hardware schematics, firmware, and desktop software available

Use Cases

  • Seismology & Earthquake Research: High-fidelity data for scientific analysis
  • Citizen Science: Deployable anywhere, contributes to global monitoring networks
  • Structural Health Monitoring: Track stress on bridges, buildings, etc.
  • STEM Education: Real-time data for hands-on earthquake demos
