What sensors are there in smart wear?

What sensors are there in smart wear? Among the sensors of smart bracelet, motion sensor is the most basic. It includes acceleration sensor, gyroscope, electronic compass sensor, atmospheric pressure sensor, etc. among them, acceleration sensor and gyroscope should be familiar to everyone. By measuring direction and acceleration force, we can judge whether the equipment moves, so as to achieve the purpose of step measurement, By matching the collected data with the types of sports that users are doing, and then monitoring the number of walks and calorie consumption of users, the most basic functions of intelligent devices can be realized.
