Product Overview

Ligo BLE Adapter is an intelligent communication and integration module designed to enable seamless connectivity between wireless fuel level sensors (BLE) and GPS/telematics devices that do not natively support BLE communication.

Acting as a protocol bridge, Ligo Adapter allows existing GPS systems to integrate wireless fuel sensors without hardware modification or replacement, significantly reducing deployment and upgrading costs while enhancing system flexibility.

In addition to protocol conversion, Ligo Adapter functions as a SUM Data, capable of simultaneously connecting to 10 wireless fuel sensors and aggregating their data for transmission to the GPS device via standard wired interfaces such as RS232, RS485, and Analog/Frequency (AF).

To ensure reliable wireless performance in challenging environments, Ligo Adapter incorporates a BLE receive-path signal amplification mechanism, improving receiver sensitivity and extending the effective communication range of wireless fuel sensors. This feature is particularly beneficial in environments with high attenuation or electromagnetic interference, such as vehicle cabins, metal fuel tanks, and industrial machinery.
