Reliably detect over 14 flammable gases

The Elios 3 Gas Warning Sensor can detect and quantify over 14 of the most common combustible gases — including hydrogen — with a resolution of 0.1% LEL (Lower Explosive Limit), reporting both gas type and concentration. It can identify even the slightest changes in gas levels and provide early warnings, enhancing safety across a wide range of operational scenarios.

Gas Formula Class Accuracy (0-50% LEL)
Butane C₄H₁₀ Class 4: Light Gas ±5
Ethane C₂H₆ Class 4: Light Gas ±5
Hydrogen H₂ Class 1: Hydrogen ±5
Isobutane HC(CH₃)₃ Class 4: Light Gas ±5
Isobutylene C₄H₈ Class 4: Light Gas ±5
Isopropanol C₃H₈O Class 4: Light Gas ±10
Methane CH₄ Class 3: Methane / Natural Gas ±3
Methyl Ethyl Ketone C₄H₈O Class 5: Medium Gas ±6
Octane C₈H₁₈ Class 6: Heavy Gas ±12
Pentane C₅H₁₂ Class 5: Medium Gas ±6
Propane C₃H₈ Class 4: Light Gas ±5
Propylene C₃H₆ Class 4: Light Gas ±5
Toluene C₇H₈ Class 6: Heavy Gas ±12
Xylene C₈H₁₀ Class 6: Heavy Gas ±5

Comprehensive in-flight reading

When the drone is powered on, the Flammable Gas Sensor automatically activates, displaying gas concentrations in % LEL directly in the Cockpit App. If the gas concentration reaches the user-set threshold, a warning will appear on the screen to alert the pilot.

Adjustable LEL threshold

To prevent false alarms and ensure timely detection of hazardous gas concentrations, the pilot can manually set the LEL threshold of the sensor before flight, customizing alerts to fit specific environmental and operational needs.

Keep-alive functionality during battery handling

To ensure continuous operation, the Flammable Gas Sensor functions independently of the drone’s power supply, allowing the pilot to change the battery without needing to redo the bump test or sensor initialisation, which must be performed in clean air. This follows a similar workflow to traditional sensors.

Compatible with other Elios 3 payloads


A connector has been integrated into the Flammable Gas Sensor, allowing other Flyability payloads to connect to the drone through the sensor. For example, the LEL sensor can detect flammable gases while the UT payload measures material thickness.

With Molecular Property Spectrometer™ (MPS) technology

The Elios 3 Flammable Gas Sensor utilizes NevadaNano’s advanced MPS™ technology for detecting flammable gases. With its cutting-edge measurement capabilities and built-in self-test features, the MPS™ sensor provides the most accurate readings on the market and eliminates the need for field calibration, ensuring reliable performance in challenging environments.
