A Smart Agriculture startup.The goal was to use IoT to improve farming practices.Worked with sensors like soil moisture, temperature, and rain sensors.Used ESP32 and Arduino to connect and control these sensors.Data was sent using MQTT, HTTP, and LoRa protocols.visualized the data using ThingSpeak and Blynk apps.And automated irrigation based on real-time soil data.learned how to build smart systems for agriculture.

Technologies & Tools :

deployed various sensors to collect vital agricultural data:

Soil Moisture Sensors: Monitored the water content in soil to determine irrigation needs.

Temperature Sensors (like DHT11/DHT22): Tracked ambient conditions affecting crop health.

Rain Sensors: Helped in detecting rainfall to optimize water usage and avoid unnecessary irrigation.

To control and communicate with these sensors,microcontrollers:

ESP32: A powerful microcontroller with Wi-Fi and Bluetooth, ideal for real-time data transmission.

Arduino UNO: Easy to program and perfect for prototyping sensor-based systems.

Data collected from sensors was transmitted using different IoT communication protocols:

MQTT: Lightweight messaging protocol used for real-time data exchange between devices.

HTTP: For sending data to web servers or cloud platforms.

LoRa: A long-range, low-power wireless protocol, suitable for transmitting sensor data in large agricultural fields where internet access is limited.

cloud and mobile platforms for data visualization and control:

ThingSpeak: Allowed us to view real-time graphs and analyze sensor data on the cloud.

Blynk App: Helped in creating mobile dashboards to remotely monitor and control irrigation.

One of the major achievements was automating irrigation systems. Based on real-time soil moisture data, the system would trigger a pump to water the field — only when necessary. This conserved water and improved crop health.
