Wireless Liquid level indicator Using LORA and ESP32

Abstract

The proposed method is an innovative solution to address the demand for effective, economical remote monitoring system of liquid levels in diverse industrial, agricultural, and environmental settings. By leveraging the ESP32 microcontroller and Long-Range (LoRa) communication technology, the system enables real-time data acquisition and transmission over long distances. Its key components include an ESP32 development board, adaptable ultrasonic or pressure sensors for liquid level measurement, and LoRa modules such as SX1278 for wireless data communication. The system's adaptability to different sensor types ensures versatility across various liquid types and container shapes. Programming the ESP32 using the Arduino IDE or Platform IO, along with relevant sensor libraries and LoRa communication protocols, facilitates continuous data collection, processing, and secure transmission via LoRa, ensuring data reliability. Noteworthy features include long-range communication capability, low power consumption for extended battery life, real-time data accessibility for prompt decision-making, scalability for monitoring multiple containers simultaneously, customizable alerts and notifications, and data logging for historical analysis. This system finds applications in monitoring liquid storage environments, flood detection, irrigation management, and ensuring the safe operation of industrial processes, providing a comprehensive solution for liquid-level monitoring needs.
