ADXL362 Applications
Pedometer is widely used in home healthcare products, it can work with SpO2, blood pressure, heart rate, respiration rate, etc. to monitor the user fitness everyday even the sleep qualityfitness everyday, even the sleep quality.
As long as the product is smaller and the requirement on the monitoring time is longer, the built in battery has to be g , ysmaller and the system current has to be lower.
ADXL362 has the lowest power consumption on the market and its built inconsumption on the market and its built in deep FIFO can help to realize system low power, make it very suitable for such applications.
The picture shows the 24/7 activity monitor product from Withings (http://www.withings.com/en/pulse) by using ADXL362using ADXL362.

ADXL362 Applications
There are multiply operation modes for consumer products UI, from button to touch and motion recognition. The picture below shows the watch which used ADXL362 to do motion recognition. When user receive the call or email, the watch will vibrate to remind the user, the vibration can be stopped by tapping the watch.Th d t lik t h h lt hi h i t t ti th The products like watch has ultra high requirement on current consumption, the lowest power consumption accelerometer ADXL362 is the best for this.
