Researchers have developed a new method of monitoring the environment using dragonflies. The team attached small, lightweight sensors to the insects to collect data on air temperature, humidity, and pressure, as well as carbon dioxide levels. The sensors were placed on the dragonflies' thoraxes and recorded data every 2 seconds for up to 5 hours. This approach could provide valuable information on environmental conditions, especially in hard-to-reach areas. The findings highlight the potential of using dragonflies as bio-sensors for monitoring climate change.
