CO₂ and propane sensors for automotive safety
100%
of currently used refrigerants potentially harm the environment
Only natural refrigerants provide long-term sustainability, if we can harness them safely
30k
ppm CO₂ can be exceeded in parked cars
Slow R744 leaks can raise CO₂ levels to potentially hazardous concentrations
Grams
of propane can create an explosive environment
A usual R290 charge can release enough gas to form a flammable layer on the floor of a small garage
Safety through real-time leak detection
To address these risks, advanced sensors have been developed to provide real-time detection and alert systems. The integration of such sensors into vehicle HVAC systems enables continuous monitoring of cabin air quality, ensuring that any leaks are promptly identified and addressed. This proactive approach not only enhances passenger safety by preventing exposure to harmful gas concentrations but also ensures compliance with environmental and safety regulations.
Our solution
The SACD sensor module combines innovation, precision, and efficiency in one compact solution. Using advanced photoacoustic technology, it ensures reliable detection of CO₂ or propane leaks. Its compact design allows seamless integration, while support for LIN and always-on 12V systems, including bus wakeup capability, simplify implementation. With low-power operation and customizable alert thresholds, the SACD enables continuous, energy-efficient safety monitoring tailored to automotive needs.
