We simulated a small situation of the fridge, open the door for several minutes, detecting the environment inside the fridge and then gather the data. For this lab, we focus on temperature, pressure, humidity and light.
- Data Analysis
How to get those timestamps:
Open door: the value of light sensor increases suddenly
Close door: the value of light sensor decreases suddenly
Humidity peak: after closing the door, the first peak value of humidity sensor
Humidity cover: the timestamp that the value of humidity sensor keep stable for some time after peak value.
Temperature peak: after closing the door, the first peak value of temperature sensor
Temperature cover: the timestamp that the value of temperature sensor keep stable for some time after peak value.
Having those timestamps, we can calculate the refrigeration time of each fridge and get the period of time that each fridge needs to decrease the temperature by 1 degree. Then we can compare the refrigeration property of two fridges.
