Week 6 & 7 - Sensor Integration

In the final stages of the building and testing phase, the group tested the functionality of the sensors working together as a single unit. A system of sensors and LEDs was set up with the microcontroller via the breadboard circuit to verify that the temperature and humidity sensor, photocell, and soil moisture sensor were all working simultaneously to read data from the environment and that the microcontroller was able to process this data and make the appropriate decision based on the algorithm.

In the video, you can see Natasha testing to make sure that the sensors and LEDs are integrated correctly. You will notice that at first, the temperature and humidity LEDs (indicated by the red and green respectively) were off because the temperature and humidity values were outside the appropriate range, but the moisture and light readings were within ideal range so the blue and yellow LEDs stayed on.

Once Natasha pressed enter on her computer, all the LEDs turned on because the values that each sensor was reading fell within the ideal range.

Successful testing of this setup has allowed the team to make significant progress towards the final prototype of the model. In the next few weeks, the team will work together to bring the project to completion and document their findings.
