Last week, I worked with Hiroko and mainly focused on connecting ESP32 to AWS. I set up AWS IoT, DynamoDB, and Lambda so that I can receive data from ESP32 via Lambda functions and store them inside of DynamoDB. I was also able to send data from my terminal to ESP32 by using API endpoint and curl. Therefore, the website can now show the most recent status of the greenhouse by fetching data from DynamoDB.
This week, I focused on improving the website UI a bit and also wrote a function so that curl command can be sent from python script or website backend, instead of sending the command directly from terminal.
So far, I think I’m on schedule. I still need to figure out how to send back data efficiently to ESP32 but this can be done as we calibrate our sensors. Next week, I will be working on deploying the website by AWS EC2.
