COZIR Low-Power Sensor Winner of Development Project

Gas Sensing Solutions Ltd (GSS), maker of the low power COZIR Ambient and COZIR Wide-Range CO2 sensors offered by, will partner with the University of Glasgow in a collaborative research & development project to build next-generation low power wireless sensor networks. 

The project will further develop GSS’ existing capability and augment gas sensor products, utilising the company’s novel low cost mid infra-red (IR) light sources and detectors, based on light emitting diodes (LEDs) and photodiodes (PDs) respectively. The LED/ PD combination are currently used in GSS non-dispersive infra-red (NDIR) carbon dioxide (CO2) gas sensors and are the lowest power consumption NDIR CO2 sensors on the market. 

This replaces the conventional incandescent light bulbs and pyroelectric detectors used in standard NDIR gas sensors. Energy per gas concentration measurement is reduced by a factor of typically 100-700, enabling sensors to be powered by battery and energy harvesting technologies over an extended operating life time. 

The TSB Collaborative project aims to reduce mid IR LED/PD power consumption via a technical strategy which benefits from the University of Glasgow`s world-class research capabilities in nanophotonic technologies. These strategies require nano-precision manufacturing processes and a key project aim is incorporation of new processes into existing supply chain based on standard semiconductor manufacturing. This includes use of GSS` existing production capability for mid IR LEDs/ PDs. 

The project will further develop semiconductor based manufacturing processes for cost effective high volume production and provide a manufacturing supply chain to implement new processes and devices together with multiple routes to market.
