Last week, I was able to go to the ECE lab to solder the light intensity sensor and connect it to the ESP32 board to obtain the sensor readings. Now I have all of the sensors connected to the ESP32, and can obtain all of the sensor readings. I also worked with Kanon to set up the connection between AWS IoT and ESP32, and was successfully able to send data to AWS and receive data from AWS. Also, I spent a substantial amount of time last week finishing up the design review report with my teammates.
This week, all of the components for the relay controlled outlet box arrived, so I soldered and assembled all of the parts. I also wrote Arduino code to be able to control the relays from messages received by AWS, which Kanon and I tested by actually using the website backend to remotely control the relays.
Overall, I think I am on schedule. Next week, I plan on calibrating and testing the individual components of the greenhouse and planting the pea shoot seeds so that they are ready by the interim demo. I want to measure the flow rate of the water pump, light intensity of the LED plant lights, sensitivity/accuracy of the soil moisture sensor, etc., so that Kanon can use the information to create an algorithm to determine when to turn the system on/off.
