# Customized Volcano-Monitoring Drones The 'little-RAVEN' Drone is Built on a DJI Mavic 3 By Michael Hemsworth | Published 2022-12-21 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/littleraven References: [newatlas](https://newatlas.com/drones/little-raven-drone-predict-volcanic-eruptions/) & [uni-mainz.de](https://www.uni-mainz.de/presse/aktuell/16822_ENG_HTML.php)  The 'little-RAVEN' drone (Remote-controlled Aircraft for Volcanic EmissioN analysis) has been developed by professor Thorsten Hoffman and a team from the Jonannes Gutenberg University Mainz as a way to track volcano activity. The drone is built on a [DJI](https://www.trendhunter.com/trends/dji-mini-3-pro) [Mavic 3](https://www.trendhunter.com/trends/dji-mavic-3) and is equipped with with an [ESP32](https://www.trendhunter.com/trends/seeed-studio-reterminal-sticky) microcontroller/WiFi module along with miniaturized sulphur dioxide and carbon dioxide sensors, a GPS module, a small air sampling pump and a flash memory drive. Each of the additional devices is powered by a 1,300mAh battery separate from the one used to power the drone to make it perfect for capturing ample data from volcanic locations. The 'little-RAVEN' drone weighs in at just 2.7-pounds and was successful tested this past April on the Vulcano island in Italy.
