Question 1

Characterize the sensors’ performance and operation. Are they all working properly at all times? Can you detect any unexpected behaviors of the sensors through analyzing the readings they capture? Limit your response to no more than 9 images and 1000 words.


Response

As the sensors are supposed to be taking readings at every hour of the day, we would like to know if there are any missing records. Hence, a dashboard was developed with interactive filters (i.e. select sensor, month and chemical) to enable the viewing of captured readings on an hourly basis.

Observations: There are indeed many missing records spread across all months, sensors and chemicals.
