Motion Sensors - Accelerometers

An accelerometer is an electronic device used to measure acceleration, and it is often used in motion sensing and navigation devices. ADXL001-70BEZ accelerometers are especially suitable for applications that require high linearity and accuracy. The device can measure a wide range of acceleration values, from 0 to 70 g.

Application Field

ADXL001-70BEZ accelerometer provides high linearity and accuracy when measuring acceleration at a variety of g levels. Its application fields include automotive accelerometers, airbag deployment systems, controls systems, power steering systems, security systems, MEMS navigation systems, and gaming devices. The device can also be used to measure acceleration in acceleration-only navigation systems and to detect motion anomalies.

Working Principle

ADXL001-70BEZ accelerometer works based on a piezoelectric effect. When acceleration is applied to the device, it creates a voltage differential in response. The magnitude of the created voltage is proportional to the applied acceleration. The device also has an integrated temperature sensor to help keep the device output stable by compensating for variations in temperature.

The ADXL001-70BEZ accelerometer is built with an anisotropic-silicon specific micromachining technique. It is a single-axis accelerometer with integrated seismic mass and support structure, along with a fixed-gap transducer. The isolated seismic mass moves within the gap in response to acceleration, which produces a variation in capacitance. The output of the transducer is then compared to a reference voltage and processed by the internal electronics.

Features

The features of the ADXL001-70BEZ accelerometer include low noise, wide bandwidth, high linearity, and low power consumption. It supports both digital and analog outputs. This device also features a programmable interrupt source, which enables the user to set thresholds that trigger the interrupt pin when the acceleration exceeds a certain value.

This accelerometer is rated for an operating temperature range of -40 degrees Celsius to +85 degrees Celsius and can withstand shock and vibration up to 10g. The device also offers low power consumption, with a typical sleep and measure current of only 0.073mA.

Conclusion

The ADXL001-70BEZ accelerometer is an incredibly accurate and reliable device, suitable for a wide range of applications. It offers low noise, wide bandwidth, and high linearity, with low power consumption. With its integrated temperature sensor and programmable interrupt source, the device is an ideal choice for automotive accelerometers, airbag deployment systems, controls systems, power steering systems, security systems, MEMS navigation systems, and gaming devices.
