When our customer installed a fuel sensor on a container truck, they faced a familiar problem: the auxiliary fuel tank was positioned over 13 meters away from the telematics tracker.
At that distance, many wireless fuel sensors struggle to maintain stable communication.
But LIGO AIR PRO proved otherwise โ€” delivering a strong and consistent signal throughout the entire setup.
In this real-world installation, LIGO AIR PRO demonstrates its enhanced wireless capability โ€” ๐จ๐Ÿ๐Ÿ๐ž๐ซ๐ข๐ง๐  ๐ฎ๐ฉ ๐ญ๐จ ๐Ÿร— ๐ญ๐ก๐ž ๐ซ๐š๐ง๐ ๐ž ๐จ๐Ÿ ๐‹๐ˆ๐†๐Ž ๐€๐ˆ๐‘ ๐š๐ง๐ ๐ฎ๐ฉ ๐ญ๐จ ๐Ÿ‘ร— ๐ญ๐ก๐ž ๐ซ๐š๐ง๐ ๐ž ๐จ๐Ÿ ๐ฆ๐š๐ง๐ฒ ๐จ๐ญ๐ก๐ž๐ซ ๐ฌ๐ž๐ง๐ฌ๐จ๐ซ๐ฌ ๐œ๐ฎ๐ซ๐ซ๐ž๐ง๐ญ๐ฅ๐ฒ ๐š๐ฏ๐š๐ข๐ฅ๐š๐›๐ฅ๐ž.
This improvement gives customers more flexibility to install the sensor on various types of vehicles, even those with fuel tanks located far from the receiver or in hard-to-access positions.

After years of collecting customer feedback, weโ€™ve found that measurement accuracy is always the top concern when using fuel level sensors.
According to SOJIโ€™s analysis, 50% of accuracy depends on the sensor itself, while the other 50% comes from proper installation.

In practice, however, several issues often occur:
โŒ Technicians may misconfigure sensors due to limited training.
โŒ Installation steps are sometimes skipped or not followed correctly.
โŒ Managers cannot monitor installations in real time and rely on manual, unverified reports, leading to errors and inefficiency.
These challenges affect overall system reliability and increase operational costs.

๐Ÿ’ก SOJIโ€™s Solution
To solve these problems, SOJI engineers have developed two new features on the LIGO BLE Configurator App, making remote sensor management easier, faster, and more reliable.
โœ… Setting Logs โ€“ View full configuration history and compare settings before and after installation.
โœ… Installation Report โ€“ Automatically generate detailed job summaries, including technician info, sensor details, and photos.

๐Ÿ‘‰ These updates help technicians check configuration history and installation & maintenance photos directly within the mobile app, and enable managers to monitor the installation process remotely, thereby reducing on-site mistakes.

๐Ÿ” Can you see the spirit of the turtle in the design of LIGO AIR?
Look closer โ€” itโ€™s not just a design, itโ€™s a story of strength, precision, and reliability.
In Vietnam, the turtle has long been revered as a sacred symbol of wisdom, endurance, and timeless strength. Its shell represents the sky, while its underside embodies the earth โ€” a perfect balance between nature and humanity, carrying the meaning of eternity.
Inspired by this cultural legacy, SOJIโ€™s engineers crafted the LIGO AIR sensor cap in the form of a turtle shell. This is more than an engineering choice for durability and protection โ€” itโ€™s a bold statement of resilience and long-lasting reliability.
Just as the turtle stands the test of time, LIGO AIR combines cutting-edge technology with superior durability, ensuring every journey is managed and protected with confidence.
โœจ LIGO AIR โ€” Built to last.
