Design Decisions

Phase 1

We decided to use the Arduino Uno as our microcontroller for the circuit because of its ease of use, compatibility with a wide variety of sensors and relatively easy coding.

After our prototype demonstrations, we decided that the Passive Infrared sensor would not work for our project because mosquitoes are cold blooded and would not give off enough of a heat signature to be detected by an Infrared sensor.

Our prototype demonstration of the Ultrasonic sensor led us to believe that it would not be reliable or accurate enough for detecting a mosquito inside the trap.

Phase 2

After testing the 3G shield for Arduino, we decided to look for an alternative for communicating with the client since it has compatibility issues.

The KY-038 sound sensor was not optimal for our trap, we decided to switch to the MAX9814 since it’s a better sound sensor and gave us promising results.

The LoRa 1276 wireless transceiver was tested with the arduino and got a signal from it. It has some range limitations, but it’s a suitable part for our trap.

A different version of the Ultrasonic sensor was tested, we will not be using it because it gives us inaccurate readings and won’t work for us.
