I am developing a smart irrigation system as my university project and I would like to ask you some questions. Could you help me, please?

This system will measure the soil moisture where the grass is planted and according to the weather forecast will activate or not a sprinkler.

My questions are:
1. What are the soil moisture levels considered as moist soil, dry soil or wet soil?
2.How much water does the grass needs per day, per week, etc.?
3.How many millimeters of rain are needed to make the soil moist or wet?

Thank you in advanced.



There are many factors affecting soil moisture content and the required amounts needed for a healthy turf.  Grass species, soil texture, climate and exposure are a few to consider.  Below is a list of resources that should help you find the information you are after:
