Pedometer is a small device, which can usually be worn around the waist or put in a pocket to measure the number of steps and distance when a human body walks. The working principle of pedometer is to use the principles of gravity sensor and acceleration sensor to sense the movement state and direction of the body. When walking, the body's center of gravity will have a certain regularity with the change of pace, and the pedometer will convert this information into readings of steps and distances through the perception of sensors.
Pedometer can not only measure steps and distances, but also record data such as walking time and calories consumed, which is very practical for people who need to lose weight or keep fit. In addition, the pedometer can also synchronize and record data through applications on smart devices such as mobile phones, which is convenient for users to check their sports data and health status.
In modern society, pedometer has become one of the necessary fitness tools for many people. It can help people to better monitor their exercise and health, at the same time, it can also encourage people to take part in more exercise and keep healthy. Especially during the epidemic, more and more people realize the importance of good health, so pedometers are becoming more and more popular.
Common equipment for measuring instruments:
1. Tape measure: Tape measure is one of the most common and commonly used tools for measuring instruments. It is usually stored in the form of a scroll, which can be easily unfolded and measured when used. Tape measures come in various sizes and lengths, and the most common sizes are 3m, 5m, 7.5m and 10m. A tape measure can be used to measure objects of various shapes. For some irregular surfaces, the soft tape of the tape measure can be better adapted.
2. Laser rangefinder: Laser rangefinder is a kind of equipment that uses laser to measure distance. It usually consists of a laser transmitter, a receiver and a distance calculator. Laser rangefinder has the characteristics of high precision, rapidity and convenience, and is suitable for indoor and outdoor distance measurement, building measurement, topographic measurement and other fields.
3.GPS rangefinder: GPS rangefinder is a kind of equipment that uses GPS technology to measure distance. It determines the position by receiving GPS satellite signals and calculates the distance between the two positions. GPS rangefinder is suitable for outdoor sports, exploration, measurement and other fields, and has the characteristics of high precision and convenient operation.
4. Smart bracelet/watch: Smart bracelet/watch is a kind of bracelet/watch that integrates a variety of sensors and functions, and can monitor physical indicators and exercise data, including steps, distance, heart rate, etc. Some smart bracelets/watches can also be connected with other devices via Bluetooth to realize data synchronization and * * * enjoyment.
5. Mobile phone applications: There are many mobile phone applications that can be used to measure distance and steps. These applications usually use the built-in sensors and cameras of mobile phones to monitor physical indicators and exercise data, and record the data in the applications. Users can check their sports data and health status anytime and anywhere through their mobile phones.
