Specifically designed for the growing number of autonomous IoT systems, the Omron D7S provides high precision measurement of spectral intensity, allowing it to reject impulse vibration noise and only respond to genuine seismic activity. Despite its compact size, D7S features its own internal memory and I2C interface, allowing it to be readily integrated into IoT devices. Potential applications include smart electricity and gas meters, wireless sensors, industrial control panels, electricity distribution panels, fire-prevention systems, home appliances such as heaters and gas stoves, chemical plants, expressways, bridges, tunnels, roads and many more.
A key feature of the sensor is its ability to distinguish between genuine seismic activity from an earthquake or from some other source. When an earthquake strikes, the D7S uses Omron’s unique spectral intensity (SI) value calculation algorithms to distinguish between seismic activity and other movement. The sensor includes a 3-axis accelerometer, and on the basis of the resulting measurements, calculates the SI value to assess the magnitude of the earthquake.
D7S is a highly compact, surface mountable module with overall dimensions of just 9.8 × 10.9mm, allowing it to be easily added to any system. The low power consumption of just 90 microAmps standby and 300 microAmps when processing, allows the D7S to be readily integrated into battery powered systems.
