1. Product introduction
Six axis acceleration sensor beacon is a new generation of sensor product developed by Chongqing Jinou Technology Development Co., Ltd. based on beacon technology. The product can send the collected acceleration data information to the mobile phone or gateway through beacon broadcast.
1.1 Triaxial sensor
1)Triaxial accelerometer
Advantages: the advantage of three-axis acceleration sensor is that only three-dimensional acceleration sensor can be used to detect the acceleration signal when the object motion direction is not known in advance. The three-dimensional acceleration sensor has the characteristics of small volume and light weight, which can measure the spatial acceleration and reflect the motion properties of objects comprehensively and accurately.
2)Three axis gyroscope
Three axis gyroscope: simultaneously measure the position, moving track and acceleration in six directions. Single axis can only measure the quantity in two directions, that is, a system needs three gyroscopes, and one of the three axes can replace the three single axes.
Advantages: small volume, light weight, simple structure, good reliability, more sensitive and more accurate.
1.2 Six axis sensor
The six axis sensor introduced by Jinou combines the characteristics of three-axis gyroscope and three-axis accelerometer to make data acquisition more accurate and fast.
