Do you wear a smartwatch? Tracking the footsteps? How does it happen? Yes, the sensor inside the watch monitors that. Starting from automatic glass doors to humanoid robots, sensors are everywhere.

What is a sensor?

In the simplest way, a sensor is a device that detects something from the surroundings.

What happens when someone calls your name on a busy road? You will instantly look at the side of the road from where you have heard your name. Why? Because your ear has heard your name and your brain has a response to that. Yes, your ear is a sensor here..!

Quest: How many sensors does a human have? Think!

Similarly in electronics and robotics, a sensor is a device that detects some input from the environment. Another circuit, mostly a controller, will prepare the response and an output circuit will generate the output.!

what is a sensor
As like multiple sensors in our body, there are multiple sensors in electronics.

  • An IR sensor can detect an object
  • Motion sensor detects motion
  • Light sensor detects light
  • Ultrasonic sensor detects distance
  • Moisture sensor, temperature sensor, sound sensor……. Their names suggest their applications.

What is IR sensor?

  • IR sensor or infrared sensor is an electronic circuit that works on the principle of infrared light emission and reflection to detect an object.

What is LDR sensor?

  • An LDR(Light dependent resistor) or light sensor is a sensor that detects the light and responds accordingly.
  • Learn more about How light sensor works

Now let’s discuss 8 sensor projects made using Havi DIY robotics kit for beginners which are easy to execute in your science fair and electronics/robotics labs. These projects can be made with other Havi Elements packs too, mentioned specifically along with the projects.

1. Automatic street light project version 1

Sensor used: LDR/Light
How it works?
The streetlights will turn on automatically at night. Means, in the darkness, the lights will be ON and under sunlight, the lights will be off.
