Bluetooth-Enabled GPS Tracker
The H-S508L is a wired in-vehicle GPS tracker with Bluetooth expansion capabilities. It supports 2G/4G networks and multi-source positioning via BeiDou, GPS, LBS, and Wi-Fi, making it suitable for fuel level monitoring, logistics and transportation, fleet management, and construction machinery tracking. The device supports ACC detection, mileage tracking, fuel consumption monitoring, temperature monitoring, speeding alerts, power-off alerts, geofence alerts, and OTA remote updates. It can be expanded via Bluetooth to include wireless sensors for fuel level and temperature, and supports RS485/RS232 peripheral communication, facilitating integration with various in-vehicle monitoring devices.
The H-S508L features a modular design and is suitable for projects requiring real-time positioning and vehicle status management. The device determines vehicle location using BeiDou and GPS, combined with LBS and Wi-Fi-assisted positioning, to provide stable positioning and tracking data even in complex environments.
The product supports wired installation and operates within a voltage range of 9–90V DC, making it compatible with 12V and 24V vehicles and certain wide-voltage vehicles and construction equipment. It features a built-in 200mAh industrial-grade lithium-polymer battery that triggers a power-loss alarm and provides short-term backup power when the vehicle’s main power supply is cut off.
The H-S508L’s Bluetooth functionality can be used to connect to external devices such as Bluetooth fuel level sensors and wireless temperature sensors; it also supports RS485 and RS232 serial port expansion. The device can upload location, ACC status, mileage, fuel level, temperature, and alarm data to the FOFN platform or the customer’s own platform, enabling remote, visual management of vehicles.
