BirdSense

‘BirdSense’ is designed to scare the birds in cities by eliminating the use of nets, which is a hassle to install and also often injures birds when they get stuck in them.

Idea

Using Bird Nets to keep them away seems like a simple solution to keep the birds away from entering into the house. But the other issue is that it often injures the birds when they get stuck into these nets and they attempt to free themselves

Problem statement

To build a Bird Deterrent which is not harmful or sharp and just scares the birds away from coming towards the building.

Constraints

  • Should not create fire hazard
  • Should not cause damage to roof and ceiling areas
  • Should not harm birds physically
  • Should be easy to install

Final Solution

     This device has a PIR sensor to detect the entry of the birds in the balcony, a speaker to trigger the thud sound to shoo away the birds.

     Using a laser cutter, a small box was made from 3.5mm MDF wood. Inside the box was a simple circuit. The device was placed on the balcony railing as shown in the image.

     The sensor was detecting the movement from nearby leaves on branches, a small piece of plastic was applied between the sensor and the frenzel lens. This however reduced the accuracy of detecting an object in its proximity but it also prevented any false positives.

     This experiment was super successful and had zero false detections, the buzzer only buzzed when I put my hand in front of the sensor or a pigeon came. However, the only issue I learnt was that the PIR sensor would be able to detect a bird if it came from the range between the red lines drawn as shown in the sketch.
