Design And Implementation Of A Microcontroller Based Gsm Alert Farm Monitoring System

ABSTRACT

This project is a farm operation monitoring system using a microcontroller device that

gets the status of the farm by using the following factors: soil moisture, temperature,

light and humidity and send the status of the farm to the user using a SMS alert

notification system all at a given time. In the field section, the Farm monitoring

system was built around three sensor modules, and will be programmed using to read

in data from a monitoring device that will be attached to the sensors.

The system uses hardware components, as well as software, thereby making it an

embedded system. The hardware components are DHT 11 module, Moisture Sensor,

Light Dependent Resistor, a Microcontroller, and a monitoring device. In addition we

will use a GSM Module to send SMS alert notification to the user.

The DHT 11 module is used to measure the temperature and humidity of the soil, the

moisture sensor is used to measure the soil moisture, the Light Dependent Resistor is

used to measure light intensity, the Microcontroller serves as the master control for

the entire system, and the monitoring device will record the properties of the soil

gotten from the DHT 11 module, the moisture sensor and the Light Dependent

Resistor. All the properties of the soil gotten through the monitoring device will be

sent through the GSM sensor to the user's GSM device.

At the end of these research work, The microcontroller based farm monitoring system

was able to get the soil moisture content, temperature, humidity and light and light of

a farm at a particular time and send the status via SMS notification alert system to the

farmer.
