Wren Sensing is developing a gas sensing platform that uses light to measure methane, carbon dioxide and ethylene. We work with partners to develop sensors for their applications.

Methane and carbon dioxide · Livestock field trials
On a working farm, we measure methane and carbon dioxide with cattle and sheep. Methane readings are compared with an existing methane sensor; carbon dioxide has so far been checked against an existing sensor in the laboratory.
Ethylene · Target application
We are developing an ethylene sensor targeting tens of parts per billion (ppb), to monitor stored fruit where ethylene must be distinguished from other volatile organic compounds.
Methane and carbon dioxide · Development opportunities
We are looking for partners to develop methane and carbon dioxide sensing for gas plants, wastewater facilities and other industrial sites.
Ethylene · Exploratory applications
Ethylene monitoring in orchards is exploratory. We invite research proposals.
Existing laser-based sensors match only one absorption line of a gas; we can match over 50. This keeps measurements highly specific where humidity or other gases interfere.
Our sensors are designed to measure parts per million (ppm) or even parts per billion (ppb). We evaluate performance for your gas and conditions.
By selecting absorption lines from each gas, we can measure several gases in one sensing system at minimal extra cost.
Each sensor is tested automatically against calibrated gas canisters, and we run selectivity tests with interfering gases present. Our sensor technology is powered by University of Sydney research: a 2024 laboratory study demonstrated the grating approach using acetylene (C2H2) as a test gas. Our sensor has improved even more since then.
