THUNDERMILL01 is an open-source Electric field mill sensor for static, portable and airborne measurements. The device is equipped with open-source software that provides high flexibility from the point of view of data output. The sophisticated design of the sensor provides the ability to use the sensor for many applications. The sensor can be operated statically at a fixed location or on mobile measuring devices or may be mounted on unmanned aerial vehicles.
Version for airborne measurements on board UAV
In the case of airborne measurements by UAV, the sensor is intended to be used with the TF-ATMON. TF-ATMON system provides real-time data transmission to the ground station where it is visualized in a 3D map and provides the drone operator with a fast and flexible response to the measured data.
The sensor is commonly operated and equipped on the ThunderFly TF-G2 autogyro drone. In that case, the THUNDERMILL device is connected to on-board avionics as is displayed in the following diagram.
Portable Version for car or stationary measurements
In the case of stationary or portable use, there exist rugged outdoor variants.
