MMA7360L Application Field and Working Principle MMA7360L is a small and low power 3-axis accelerometer with a built-in temperature sensor. It is designed for low power applications in various monitoring and alarm systems. It has high shock survivability and low power consumption. The MMA7360L is a digital output device, operating in two modes – pulse mode and pulse/burst mode.Application Fields of MMA7360LThe MMA7360L can be used in various applications like:

• Alarm and monitoring systems
• Wearable and implantable devices
• Telemetry systems
• Portable medical instruments
• Inertial navigation systems
• Robotics applications
• Wireless data transmission
• Vibration measurement
• Movement and position sensing
• Automotive safety and control systems

Working Principle and Features of MMA7360L The MMA7360L accelerometer works on the principle of capacitive differential pair sensing. The object to be detected is placed on a suspended mass with spring mechanism. As the object is subjected to a force or motion, the suspended mass moves causing a change in the capacitance between two plates. This change in the capacitance is sensed by the device and converted in to digital output data, which is available on the 3-pins on the accelerometer. The MMA7360L accelerometer features a three-axis sensing. It features a low power operation with a 3V detection range. The device is highly shock resistant and resistant to mechanical vibrations. It is factory calibrated for temperature compensation. There is an in- built temperature sensor which can detect temperatures up to 200°C. Also the device can operate in two modes – pulse and pulse/burst mode.ConclusionThe MMA7360L accelerometer is a small, low power and highly resilient device featuring a 3-axis sensing mechanism. It can be used for various applications in alarm and monitoring systems, wearable and implantable device, inertial navigation systems and telemetry systems. The working principle of the accelerometer is the capacitive differential pair sensing where the change in capacitance is reflected as digital output. The device is also highly shock resistant and robust and can operate in two modes.
