Total solution of SensorHUB-IC and Sensor
Reliable and easy to use heart rate monitoring devices are a key component to improving one's health.The SensorHUB-IC and Sensor solution is a heart rate monitoring system for use in wearable devices, featuring a Megahips SensorHUB-IC and Murata sensor Since this solution omits individual design for SensorHUB-IC and sensor, you can start up immediately. In situations where the wearable device is continoulsy monitoring vital data, battery life is certainly a key issue. The "frizz" high level processing capability and low consumption results in a longer life battery.
Features
Solution suited for wearable devices
Solution suited for wearable devices
■The extended life of the wearable device's battery made possible by the low consumption Sensor HUB-IC and Sensor.
■An algorithm cancels the noise resulting from body movement.
■Align with functions of another sensor
For example: PDR(Pedestrian Dead Reckoning) with Murata pressure sensor.
