Researchers from the Laser Gas Spectroscopy Group University of Technology are developing an innovative gas sensor to detect leaks or gas emissions at distances of up to 100 metres.

Based in the department of electronics, photonics and microsystems, the group of scientists has been developing laser-based methods for precise and selective gas detection for years. So far, there have been sensors that perform point measurements, and therefore at the sensor’s location.

“For the past two years, the industrial sector has been asking us about the development of a laser gas sensor that would enable remote measurement, i.e. ‘at a distance’. This is primarily related to increasing the safety of workers”, says Dr Karol Krzempek from the Department of Field Theory, Electronic Systems and Optoelectronics. 

The researchers took up the challenge and began research to develop a prototype laser sensor that will be able to measure a selected gas at up to 100 metres. The realisation of the prototype, which will be capable of operating in non-laboratory conditions, requires the design of all components from scratch, including control and measurement electronics, optical modules, mechanical components and software. In addition, the device must be IP66-rated and meet all safety standards.

Thanks to the signing of a letter of intent with Ekosystem, the researchers were given permission to carry out tests at the Wrocław biodegradable waste landfill. The company’s employees hope that this type of technology can be used in the future in their everyday work. They hope that the solution will allow even better control of the composting process, increasing the value of the fertiliser produced and at the same time minimising greenhouse gas emissions.
