January Updates
What Trout Lab Accomplished
So far, in January, we have completed everything that we planned to do by the 25th of January. We ordered and received our parts, which includes our Temperature sensor, ORP sensor, camera, and other important materials for our device. We successfully calibrated, tested, and set threshold values for each of our sensors. We are able to receive SMS text message alerts if on of the sensors reach over their threshold value and if there is light exposed in the tank. We decided to use the camera as our light sensor to lower the cost and material use. We found a more convenient way to remotely control the chiller, by building a smart power outlet using a 2 channel DC 5V Relay Module with Optocoupler Low level Trigger. The plan was to utilize a PHP webpage to update a database via a websocket on the RPi. However, after much consideration we determined this method to be too taxing for large scaling and moved to a more passive method. This also lead to a change in the server language we use from PHP to JavaScript because it has both markup and programming utilities. After some experimentation, and setup we were able to get a web page able to interact with a dummy table on a MySQL database.
