THUNDERMILL01 is an open-source Electric field mill sensor for static, portable and airborne measurements. The device is equipped with an 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.
In case of arborne measurements by UAV the sensor is intended be used with TF-ATMON system. 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 equipped on the ThunderFly TF-G2 autogyro drone. In that case the THUNDERMILL device is connected to on-board avionics as is displayed in following diagram.
In case of stationary or portable use, there exist rugged outdoor variant.
The device itself consist the datallogger and GPS unit to store measured values captured with precision timing.
For demonstration of electric field mill technology there is simple demonstrator, with functional parts completely exposed. That variant is usefull as a school demonstrator.
