Software Requirements Specification
for
Aquaponics: Growing fish and plants
together by using IoT
1. Introduction
1.1 Purpose
The purpose of this system is to limit the water usage, the amount of waste materials in the water
and the need for synthetic vegetable fertilizers. Aquaponics also allows to build horticulture
farms in areas where this normally would not be possible: polluted soil, urban areas or infertile
areas.
1.2 Document Conventions
In our system mainly two users are there; first one is user who uses a system and second is
admin. But in the SRS, we are taking one user, because the operation performed by admin is
done manually.
1.3 Intended Audience and Reading Suggestions
Audience of this SRS are other project developer, users like students, viewers that will use
system. This SRS contains detail description about the product, its functioning, different external
interfaces required, system features, Nonfunctional requirements and some additional
requirements.
1.4 Product Scope
Our project implements an IoT system in Aquaponics to check the parameters of water so that it
can be used for nourishing the plants and the fishes growing in them. The one of important parts
is the bacteria which converts the fish waste into manure for plants. The entire system is
monitored as variation in the levels of from optimum range will lead to the death of plants and
fish. The project includes ESP32, Sensors like TDS, PH, temperature & humidity sensor for
transmitting data over the internet. The value transmitted by the microcontroller is shown on
LCD as well as on mobile application can control the water pump through it. The detected value
is sent as a message to the farmer.

2. Overall Description
2.1 Product Perspective
The proposed system contains the following sensing elements – temperature sensor, pH sensor,
TDS sensor, Water level sensor. The temperature and pH sensors are placed within the tank that
monitors the temperature and pH levels. These sensors are always necessary to observe the
system. Just in case of any variations within the data, an alarm is given to the farmer to check the
aquaponics setup. Variations principally occur because of abnormality within the original setup.
The fishes should be prevented from getting infected, however, if any fish is infected by a
specific sickness, the sickness would spread rapidly among the other fishes within the tank. The
entire block diagram of the system is shown in Fig.1. these sensors data will be sent on cloud and
monitor through mobile application.
2.2 Product Functions
Sensing Parameters- Temperature, PH Level, TDS, Soil Moisture, Water Level
Store data on Amazon AWS or Google Cloud.
Visualization and patient monitoring on Web and Android App.
Fully Wireless
Protocol Used: MQTT
Realtime notification to user.
2.3 User Classes and Characteristics
In our system have mainly two users, first is the who uses a system and second is the admin.
user: user can only monitor parameters and ON/OFF system manually.
Developer: These users has an authority to update, schedule and Configure a system.
2.4 Operating Environment
Our project is based embedded system and user application runs on iOS and Android platform.
So we need android or iOS smart phone to run the application.
2.5 Design and Implementation Constraints
There are three major components for our system are admin panel, cloud and ESP32 with
working internet connection.
2.6 User Documentation
User manual will be provided with this system.
2.7 Assumptions and Dependencies
Only assumptions in the system is that user has knowledge of smartphone and internet.
3. External Interface Requirements
3.1 User Interfaces
The user must have an Android or iOS application or system with working internet connection.
3.2 Hardware Interfaces
No any hardware interfaces needed except access point.
3.3 Software Interfaces
Our project is based on cloud application so cloud account and subscription must be done.
3.4 Communications Interfaces
The internet connection plays important role which is updating the notice in real-time.
4. System Features
4.1 System Feature 1
4.1.1 Description and Priority
Measure Water Quality and turn of pump & Grow Lights: Priority is high
4.1.2 Stimulus/Response Sequences
Sensors stop sensing while water pump turn on except level sensor.
Run system in manual mode when not connected to cloud (Internet).
4.1.3 Functional Requirements
• Scheduling system to work autonomously.
• Assigning role to user groups.
• Setting peak values for each sensor.
5. Other Nonfunctional Requirements
5.1 Performance Requirements
The system should take immediate action when water quality is not good for fish.
5.2 Safety Requirements
The maintenance should not be done without turning off power supply.
5.3 Security Requirements
Here the embedded system-based system and data is on third party cloud so, there is no need of
security mechanism.
5.4 Software Quality Attributes
• Reliability
The reliability that anyone can easily view the alerts or notifications and admin and easily
manage the notice/ads.
• Availability
System will available at all time until power or internet problem. If we provide backup power
supply, then we can say that our system availability is 100%.
• Maintainability
Our system usually not required maintenance until some modification to be done.
• Portability
The application is works on both android and iOS platform.
6. Other Requirements
We require a working internet connection to update from cloud.
