Sumit Sharma

Sumit Sharma has rich experience in Unmanned systems with specialization in Drones architecture development and testing for different applications. He is experienced in Drone Mechanics, Avionics, Design and manufacturing. In his early career, he was involved in the development and testing of the first approved agriculture drone and later getting it approved by the DGCA. Along with this, he has contributed to the development of a Survey drone for Aerial Surveys. He was also involved in the development of high speed and long range surveillance drones for defence tenders. Sumit has been involved in early agriculture spraying pilot projects and was a part of Aerial Spraying on the Locust which hit Rajasthan in 2020.

Voltage and current sensors and their roles

Current and voltage measurements in drones are essential for monitoring the electrical system’s health and power management of the drone, particularly the consumption and battery status. Let’s see how voltage and currents are measured using different onboard sensors:

  • Current measurement:
    • Sensors: Generally, a Hall-effect current sensor (for example, ACS712) is used to measure the voltage and current flow.
    • Working: Hall-effect sensors detect the amount of magnetic field generated by the flow of current through a conductor. The sensor outputs an analog voltage proportional to the current strength, which is then read by the flight controller to make respective decisions.
    • Interface: Analog voltage is usually fed into an analog-to-digital converter (ADC) on the flight controller, providing a digital representation of the current.
  • Voltage measurement:
    • Sensor: Voltage divider or voltage measurement IC (for example, INA219,...
