Presentation Transcript

  1. Technical University – Sofia Bulgaria Atmospheric electrostatic field acquisition system with charge sensing TsvetanMarinov & PetyaPopova Advising Professor: MityoMitev European Analog Design Contest 2013

  2. What is Atmospheric electrostatic field? SENSOR Technical University – Sofia Bulgaria European Analog Design Contest 2013

  3. Project goals:  Develop “Field Mill” sensor Use charge amplifier instead of I-V conversion Ensure input range of +/-30kV/m Implement on-board data logging Implement live data stream and device control via radio Ensure full weather proof enclosure      Technical University – Sofia Bulgaria European Analog Design Contest 2013

  4. System architecture ADC: ADS8519 MCU: MSP430FR5739 Field Mill Sensor Charge Amplifier: IVC102 Electrostatic Field Acquisition System Power Supply: TPS7A3001 TPS7A4901 REG101 LP38690 OPA369 Royer convertor Motor Driver: DRV8834 Technical University – Sofia Bulgaria European Analog Design Contest 2013
