Hydroponics Tracker

Background

You want to automate your indoor garden setup. Being a crafty, nerdy type of person, you hooked up sensors to your plant containers, and you track metrics such as:

• container name
• pH levels
• Nutrient solution levels
• Temperature
• Water levels

Each container's data are written out to tab-delimited log files, in this format:

<timestamp>	<container name>	<pH>	<nutrient solution level>	<temperature>	<water level>

Stories

Your mission is to be able to be able to tell what the average pH, nutrient solution level, temperature and water levels were for each plant container.

Your program must, at a minimum:

• take a file path as an argument
• return a hash that has the average ph, average nutrient solution level, average temperature and average water level for each container mentioned in the file
• return the name of the container that has the highest average temperature for all of the data loaded
• return the name of the container that has the highest absolute water level for all of the data loaded
• return a hash that has the average ph, average nutrient solution level, average temperature and average water level for all of the data loaded. This is not separate for each container
• return the name of a container that has the highest absolute ph for a date range. You will provide the start date and end date

Check your work

The correct answers are:

container1

pH	nutrient solution level	temperature	water level
5.01	39.02	57.76	2.12

container2

pH	nutrient solution level	temperature	water level
5.95	19.77	73.06	3.8

container3

pH	nutrient solution level	temperature	water level
7.01	10.97	67.61	4.7

Highest Average Temperature

container2

Highest Absolute Water Level

container3

Average stats for all containers

pH	nutrient solution level	temperature	water level
5.99	23.25	66.15	3.54

Highest absolute ph for

container3
