Sparv Embedded, a Anemoment International Distributor, is working with Linköping University to integrate a high precision CH4 (methane) sensor from Aeris Technologies for UAS applications.
The sensor has an unprecedented CH4 resolution for its size, measuring variations smaller than one ppb (parts per billion). After they adapted the sensor for UAV use, the payload weighs in at 1.8 kg—light enough to be flow around 10 minutes with a fairly small quadcopter. This offers an exciting possibility for more convenient sampling of methane.
Methane is a gas with a greenhouse effect 84-times stronger than carbon dioxide when counted over 20 years after releasing the gas into the atmosphere. Accurately measuring methane emissions is important, not only in raising awareness of the environmental impact methane has on our atmosphere, but also in helping to formulate realistic and effective regulations regarding its release.If given more attention, the weight could be pushed down a lot more.
The image above shows a quadcopter hovering with the white Aeris sensor attached underneath. The quadcopter also carries a Sparvio sensor system that synchronizes data from Aeris with readings from the TriSonica Wind & Weather Sensor, GPS and other sensors. Sparvio logs all data and transmits it to a ground station to visualize on a map in real-time. In the end, the combination of all data will be used to calculate not only the location of methane emission sources, but also the quantity of gas flow.
