Problem Statement/objectives
India has 120 million farmers, out of which 30 million use smartphones
and have a basic sense of understanding about digital marketplaces, So
Every Farmer Cannot use the Smartphone applications to monitor
irrigation facilities thus Create a System using Global System For Mobile
Communication(GSM) So that User can access the Data through
Messaging system.

Objectives
Plant Monitoring System Using GSM 900A is to develop an Arduino-based system that can
monitor the environmental conditions of plants, such as temperature, humidity, and soil
moisture levels, and send SMS alerts to the user when these conditions fall outside of
acceptable ranges.
The system should use a GSM 900A module to send SMS messages to the user's phone.
The system should also be able to control the watering of the plants based on soil
moisture levels, and should include safety features to prevent overwatering.
The goal of the system is to help users maintain healthy plants by providing real-time
monitoring and control.
Solution
To design a system that can monitor and record the temperature, humidity, and
soil moisture levels of plants in real-time.
To implement an SMS alert system that can notify users when the
environmental conditions of their plants fall outside of acceptable ranges.
To include a watering system that can automatically water the plants based on
soil moisture levels, and to include safety features that prevent overwatering.
To develop a compact and cost-effective system that can be easily deployed in
different environments, including home gardens and small-scale farms.
Connections
Description
● We have Interfaced Arduino Uno with SIM900A in which Tx and Rx is connected to pin
8 and 9th of UNO Respectively and Gnd is Grounded.
● DHT11 has –ve pin which is connected to Gnd and out is connected to 4th pin of
Arduino and +ve pin to 5volts
● LM239D Dual Motor Driver is connected to water tank (M2),D3 and D4 pins to 6th and
7th Pin of UNO
● Water Level Sensor’s 5th pin is connected to A0 of UNO as well as +ve and –ve Pins to
5th pin and GND of UNO respectively.
Results (Intermediate results/simulation results)
Feasibility Analysis
●
Technical feasibility: The project uses readily available off-the-shelf components such as DHT11
sensor, water level sensor, Arduino board, and GSM 900A module, making it technically feasible
to build. The sensors and components used are also widely used in various industries, making it
easy to obtain and install.
●
Economic feasibility: The project is economically feasible as the cost of the components and
sensors is relatively low, and the system requires minimal maintenance.
●
Operational feasibility: The project is operationally feasible as it is simple to use and requires
minimal training. The system is also easy to operate remotely, making it suitable for individuals
who want to monitor their plants while away from home. The water pump and automatic
watering system can reduce the time and effort required to care for plants, making it an
attractive solution for those with a busy lifestyle.
Innovation or Uniqueness of the solution
●
The innovation and uniqueness of the Plant Monitoring System Using GSM 900A project lies in its
ability to provide a real-time monitoring system for plant growth and health.
●
The use of the DHT11 sensor to measure temperature and humidity, as well as the water level
sensor, allows the system to collect data on the plant's environment.
●
The data is then transmitted to the user's mobile phone via SMS using the GSM 900A module.
●
The system also offers the ability to monitor the plant's growth and health over a longer period of
time, which can be useful for research or educational purposes.
●
Overall, the project's innovation and uniqueness lie in its ability to provide a low-cost, userfriendly, and effective solution for monitoring plants' growth and health, allowing for better plant
care and management.
Impact or Usefulness of the solution
●
The Plant Monitoring System using GSM 900A has the potential to have a significant impact on
agriculture and gardening industries. By monitoring plant conditions such as temperature,
humidity, and water levels, the system can help farmers and gardeners to make informed
decisions and optimize plant growth.
●
Additionally, by sending SMS alerts to users, the system can help prevent plant damage due to
unfavorable conditions, thus improving crop yield and overall plant health.
●
Furthermore, the use of the GSM 900A module for communication makes the system accessible
and affordable for remote areas where internet connectivity may be limited. This project can also
serve as a basis for further development of more advanced plant monitoring systems that utilize
other technologies such as wireless sensor networks and machine learning algorithms.
Summary

The Smart Irrigation System Using GSM 900A is a project that aims to monitor the temperature,
humidity, and water level of plants using sensors and send the data to a mobile device through
GSM technology.

The system uses a DHT11 temperature and humidity sensor and a water level sensor to measure
the plant's environment. The Arduino board reads the sensor data and uses the GSM 900A module
to send the data via SMS to a mobile device.

The system also has a water pump to automatically water the plant when the water level is low.
Overall, this project provides a cost-effective and efficient way to monitor and care for plants
remotely.
