Title of the Innovation: Ammonia Gas Sensor ( visual color change type)

Brief About Innovation

Ammonia Gas Sensor ( visual color change type)

A patented technology is developed to manufacture the visual color change based ammonia sensor made on daily use paper having colour change capability under ammonia exposure.  It can be used directly after growing on paper, no device fabrication is required. It can be used as use and throw basis. This patented developed technology is available for commercial exploitation at NRDC.

Salient Features

  • the product shows: Visual colour change based alert under ammonia exposure.
  • as the sensor itself is paper based and made by dipping paper in precursor solution and hence cost-effective & easy to use; can be used as use and throw basis.
  • Patented.

Advantages

  • Fast response ( ~ 5 sec)
  • High sensitive (≥ 10ppm)
  • Visual colour change based
  • Paper Based Disposable  Technology
  • No Electronics/External Energy Source required
  • Room Temperature Operation
  • Low cost production
  • No device fabrication required
  • High shelf life
