Aim: -

To detect and count mosquitoes in a specific area.

​

Problem to be solved: -

Help to automate the mosquito repellent research and experimental work.

​

Attempts: -

1. Made a prototype using breadboard in which IR sensors were placed adjacent to each other.
   Result - The sensors didn’t worked.

2. Reconfigured the prototype when transmitter and receiver were placed parallel and facing each other falling at line of sight.
   Result - IR sensors worked to detect thin wires but failed to detect small objects.

3. Made Array of transmitters and receivers using breadboard.
   Result - IR sensors efficiency increased.

4. Made permanent connections using PCB.
   Result - Tested different ways mosquitoes can pass through the line of sight. But failed to detect mosquitoes.

5. Tried with different ADCs of different bit rates.
   Result - Sensitivity of the sensors increased with higher bit rate resolution.

6. Improved the codes efficiency.
   Result - Sensitivity increased a little, testing got easier and motion could be detected for smaller objects when compared to initial testing. But failed to detect mosquitoes.

​

Current Progress: -
Right now we are able to detect objects which are half in size in comparison to those which were detected in the initial testing. The sensors are detecting a paper of ball of about 5mm diameter when dropped from a height in a way that it passes from between the transmitters and receivers. But it still fails to detect the mosquitoes.

 

Assumed solution/ Next step: -
The next step would be to try the same setup of our project with an ADC with a higher bit rate resolution, most probably 16 bit.
