The pedometer is a healthy electronic product. As the name implies, how many steps can you calculate when you walk? Foreign experts generally recommend that taking 10,000 steps a day is the best for health, so we often see some slogans "10000 steps a day". The pedometer can help you accomplish this goal, helping you to take a look at the day and take a few steps. If you have more, you can take a few steps tomorrow. If you are less, you will take a few more steps tomorrow. This is very helpful for your health, but it can also help you lose weight, it is very simple, walking can consume calories. Nowadays, people pay more and more attention to health. If the pedometer will go to the family of ordinary people, the pedometer will have an infinite market prospect. The pedometer generally uses an accelerometer to feel the vibration of the outside world. Its working principle is that a small piece of magnet is sealed in a section of plastic tube, and the coil is wound around the tube. When the plastic tube moves, the magnet moves backward in the tube due to inertia, cutting the coil, and the coil is generated due to electromagnetic induction. When the current is moving, the acceleration of the ups and downs is approximately sinusoidal. The output current of the coil is also a sine wave. The frequency of the sine wave can be used to calculate the number of steps, the calculated speed, the distance, and the calories burned. The pedometer consists of a vibration sensor, an electronic counter, a pedometer, and a screen, a movement, and the like.
