Earthquake Sensor Omron D7S – RAK12027

The RAK12027 Earthquake Sensor, part of the WisBlock Sensor Series, integrates the Omron D7S, a highly accurate seismic sensor. Communication with the target microcontroller is via the I²C interface and interrupt pins, ensuring reliable data transfer and immediate alerting.

When an earthquake occurs with an intensity equivalent to 5 or higher on the JMA Seismic Intensity Scale, the shutoff output (INT1) is activated, allowing sensitive equipment to automatically power down. The sensor also includes a collapse detection function, triggering when the sensor tilts more than 20 degrees, indicating a potential structural collapse.

With its compact size of 10 x 23 mm, 3.3 V power supply, and low power consumption, the RAK12027 is designed for battery-powered IoT solutions and easy integration into monitoring systems.

Warning: Do not use this sensor in life-critical safety devices or applications where sensor failure could directly affect human safety.

Typical Applications:

• Earthquake early-warning systems

• Automatic shutdown of sensitive equipment

• Building stability monitoring

• IoT-based seismic and disaster detection systems
