D7S Vibration Sensor
An open-drain output. Goes active (ON) when the shutoff judgment condition and collapse detection condition are met. An open-drain output. Goes active (ON) during earthquake calculations, offset acquisition, and self-diagnostic processing. Pull up the voltage to VCC even when you do not use I2C. Pul.
D7S Vibration Sensor Helps Prevent Fire and Other Secondary Disasters after an Earthquake. The World’s Smallest Class Size Seismic Sensor. Using the SI value, which has a high correlation with the seismic intensity scale that indicates the magnitude of an earthquake, provides higher-precision judgment of seismic intensity scales. The 3-axis acceleration Sensor and OMRON’s unique SI value calculation algorithm achieve surface-mountable compact modules and low power consumption.
