Smart Agro-Industrial Monitoring System Using Multi-Sensors and ESP-NOW Protocol

The multisensor-based embedded system monitors a few sets of sensing parameters continuously and simultaneously with different data rates. These systems are highly required for remote monitoring. Constantly monitoring multisensor data leads to a high energy budget, limiting resource-constrained device usage. Hence, it is necessary to develop an energy-efficient signal quality-aware wireless sensor network system for remote monitoring and controlling Agro-Industrial based applications. A data logger for a wireless sensor network is designed using ESP-NOW protocol for collecting data from multiple sensors. ESP8266 is used for transmitting and receiving the data. The challenges in agro-industrial applications may vary with time, so this needs monitoring and leveling them. Collecting the data from the sensors and applying compression techniques minimizes cost, power consumption, speed, and latency. Run-Length Encoding (RLE) and K-RLE compression techniques are used and they are compared.
