The soil moisture sensor senses moisture of soil i.e. the water level in soil and gives this data in electric signal form and microcontroller can read that signal and process it. Piezo buzzer is actuator that works on piezoelectric effect. When we apply voltage that gets converted into vibration and that vibration in air causes the voice. In this lesson we will learn Arduino Programming. You can download Arduino ide from https://www.arduino.cc/en/software and just install it by flowing the give instructions. Once you open Arduino IDE you will get this screen Apache Kafka is an open-source, distributed streaming platform that is designed to handle real-time data feeds and high-throughput, fault-tolerant, scalable data streaming. The data format in Druid can be described as a "columnar" format. This means that data for each column is stored together in memory, making it highly efficient for analytical queries. Data loading in Apache Druid refers to the process of ingesting data into the Druid cluster for storage and subsequent querying and analysis. Data management in Apache Druid involves various processes and strategies to ensure the smooth functioning of the data store, efficient use of resources, and optimal query performance. It encompasses tasks […] We are going to cover the following topics in this lesson
