Working principle of anti loss locator

GPS locator: This type of locator has a built-in GPS chip that determines its location by receiving satellite signals. Its working principle is to calculate the distance between the device and the locator by measuring the propagation time or flight time of the signal, thereby achieving accurate positioning. The positioning accuracy of GPS locators is generally within a range of 5-50 meters, but indoor positioning may be limited.
Bluetooth anti loss device: This type of locator connects to smartphones or other devices through Bluetooth technology, using the strength and range of Bluetooth signals to locate items. Its working principle is to use Bluetooth technology combined with a smartphone app to achieve information exchange, and locate the location of the device based on the distance changes between the two. Once the Bluetooth connection is disconnected, the anti loss device will emit sound and light reminders.
UWB technology: UWB locators use ultra wideband technology to send and receive nanosecond pulse signals for data transmission, which has the characteristics of low power consumption, high accuracy, and strong anti-interference ability. Its working principle is to calculate the distance by measuring the propagation time or flight time of the signal, combined with triangulation to determine the specific location of the target device. The error range of UWB locators is usually between 1-3 meters and they can update position data in real-time.
Application scenarios: Anti loss locators are widely used in various scenarios, including but not limited to:
Child safety: Home UWB locators can help parents track their children's location in real-time and prevent them from getting lost.
Item management: Bluetooth anti loss device can be used to track valuable items, files, etc., making it convenient and quick to retrieve them.
Electric vehicle anti-theft: GPS anti-theft alarm tracker can monitor the location and movement of electric vehicles to prevent illegal movement and theft.
These technologies each have their own advantages and disadvantages, and users can choose the appropriate anti loss locator according to their specific needs.
