Monitoring System for Amaranth Cultivation Using Temperature and Humidity Sensors

Amaranth is a highly nutritious crop with significant agricultural potential. However, maintaining optimal growth conditions is challenging due to environmental factors such as temperature and soil moisture. This study presents the development of an monitoring system designed to track and visualize key environmental parameters essential for amaranth cultivation. The system integrates an ESP32 microcontroller with DHT22, HD-38, and DS18B20 sensors to measure air and soil temperature, as well as humidity levels. The collected data is processed and displayed through real-time graphical representations, facilitating decision-making for optimal crop management. Experimental results demonstrate the effectiveness of the system in monitoring environmental conditions, highlighting its potential to enhance agricultural productivity and sustainability. Future improvements include refining sensor calibration and expanding the system’s capabilities to include additional environmental variables.
