Product introduction
The nine-axis accelerometer is a new generation sensor product developed by Chongqing Jinou Technology Development Co., Ltd. based on BLE low-power Bluetooth technology.
The product integrates accelerometer, gyroscope, magnetometer and other sensor chips.
The nine axes in the product name include the X-axis, Y-axis, and Z-axis of the accelerometer, the X-axis, Y-axis, and Z-axis of the gyroscope angular velocity sensor, and the X-axis, Y-axis, and Z-axis of the magnetometer sensor, collectively referred to as nine axes.
The nine-axis accelerometer supports high sensitivity, high transmission rate, wide applicability, and easy operation.
It supports real-time and offline collection of acceleration data, and the collected data can be sent to the mobile app via BLE low-power Bluetooth technology.
The product is equipped with a basic version of the mobile app for testing various functions of the product.
If you are not satisfied with the mobile app, you can design and develop various application apps yourself, and Chongqing Jinou Technology Development Co., Ltd. will provide certain technical support.
