This week, I connected the water pumps to the relay system that I assembled last week, and measured the flow rate of the water pump. Kanon and I met up and calibrated the soil moisture sensors in order to figure out when and how long to turn the water pumps on for. I planted the pea shoot plants earlier this week, so we used the soil to test the soil moisture sensors and water pumps. We also tested communications between ESP32 and AWS by sending sensor data to AWS, using the data and user inputs from the website to determine when to turn the greenhouse components on/off, and sending the on/off commands from AWS to ESP32.
Overall, I think I am on schedule. Next week, I plan on adjusting the watering tube to distribute water more evenly to the plant, and figure out where to physically place and connect the components in the greenhouse. I will need to adjust the wire length of all of the components connected to the ESP32 and determine the specific layout of the electrical components so that I can order a case with the right dimensions to enclose the electrical components in.
