NODEMCU AND WIRELESS SENSOR NETWORKS IN AGRICULTURE: A REVIEW OF ENVIRONMENTAL PARAMETER SENSING.

In the agricultural environment, there is an increasing need for advanced techniques and systems to identify and prevent crop diseases. Various challenges such as groundwater depletion, soil erosion, emergence of new pests and diseases, land fragmentation, rural-urban migration, and the availability of power supply for farming are currently impacting the agricultural sector. To address these challenges, a system has been developed to monitor field conditions at farms in real-time, focusing on parameters such as temperature, soil moisture, humidity, and water levels. Sensors collect data, and the real-time values are stored in the cloud. The NodeMCU Microcontroller Unit serves as the main component, acting as a gateway between the field and the internet and facilitating communication of parameter values to the cloud. This system enables farmers to access critical field parameters remotely, promoting the adoption of smart agriculture practices. [ABSTRACT FROM AUTHOR]
