1. Introduction

1.1 Purpose of the requirements document

The Software Requirements Specification (SRS) is a communication tool between stakeholders and software designers. It gives a description of the software’s purpose and functionality. In other words, the SRS is a document that captures complete description about how the system is expected to perform.

1.2 Scope of the product

The project consist of upgrading a classic greenhouse to retrieve live information about its climate. These information will be available on an online dashboard.

1.3 Definitions, acronyms and abbreviations

  • Greenhouse: an area, usually chiefly of glass, in which the temperature is maintained within a desired range, used for cultivating tender plants or growing plants out of season.
  • LoRa: Long Range and low energy radio RF technology developed by Semtech. It's an open-source technology.

1.5 Overview of the remainder of the document

2. General description

2.1 Product perspective

The aim of this projet is equip all the farm, not only one greenhouse.

2.2 Product functions

At the end, product should return:

  • The air temperature
  • The air moisture
  • The soil moisture

And display these data on a graphic interface (dashboard). The checking must be do remotely.

2.3 User characteristics

2.4 General constraints

  • The energy source : There is no power near of the greenhouse, consequently we'll use a solar power.
  • Duty Cycle : We can use only 1% of the time in order to not overload the LoRa network.
  • Sensors needs to be moveable : Vehicles should be able move along the greenhouse.

2.5 Assumptions and dependencies

3.Specific requirements, covering functional, non-functional and interface requirements

  • document external interfaces,
  • describe system functionality and performance
  • specify logical database requirements,
  • design constraints,
  • emergent system properties and quality characteristics.
