Solution Overview

With the fastest response time and configurable design, our solid-state hydrogen sensor and MEMS-based nanochip are making fuel cells viable for all. .

Thanks to self-cleansing and self-calibration mechanisms, our sensors can easily withstand the harshest conditions, whether on the road or in sub-zero conditions.

The 21 Senses Advantage
  • Exceptional longevity in conditions with high moisture and contaminant levels, thanks to self-cleansing and filtration.
  • Flawless operations in both low and high-temperature conditions
    1. Solid State – Up to 65°C
    2. MEMS Sensor – Upto 200°C
  • Built to withstand high levels of hydrogen exposure
    1. 1PPM – >50,0000 PPM
    2. Solid State: 1PPM – >50,0000 PPM
  • Fastest response times at less than 200 milliseconds
  • Zero cross-reactivity with other gases
  • Ultra-compact size seamlessly fits into any vehicle design
  • Our personalized approach includes design consulting and advisory
