What is a sensor?

A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. It converts physical data to electronic data.

We frequently make use of sensors in our day-to-day life in several applications. With the advancement in drone technology, many companies have started putting sensors in their drones for collection of data. This data they collect can be used for various purposes.

Drones can make use of sensors to detect changes in their surroundings that allow them to control better and also collect critical data about the object they are inspecting.

The four major sensors in a drone are:

  1. Accelerometer

  2. Barometer

  3. Gyro Sensor

  4. Magnetometer

The future of drone technology depends on sensors in many ways. They have made inroads into many fields and it is necessary that they have the ability to detect the changes in the systems they are meant for. These sensors have helped with that and as they become more and more precise, the service provided by drones will become better.
