Earthquake click carries D7S, the world’s smallest high-precision seismic sensor from Omron. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU
over I2C interface, with additional functionality provided by the following pins on the mikroBUSTM line: PWM, INT, CS.
When an earthquake occurs with a seismic intensity equivalent to 5 Upper or higher on the JMA (Japan Meteorological Agency) Seismic Intensity Scale, the D7S will activate the shutoff output to notify the user that an earthquake has occurred.
Applications: Vibration sensor, fire prevention systems, electricity meters, gas meters, chemical plants, bridges, tunnels, etc.
MCU: D7S seismic sensor
Key Features: Low power consumption, Acceleration Detection Range −2,000 to 2,000 gal, Shutoff Output (INT1) Output at seismic intensity level 5 or higher
Key Benefits: The click can calculate seismic activity and detect an earthquake
Input Voltage: 3.3V or 5V
Click board size: S (28.6 x 25.4 mm)
