Data loggers are electronic devices used to record measurements over time. They can track various environmental conditions, such as temperature, humidity, and pressure, making them useful in fields like agriculture, meteorology, and manufacturing. Data loggers often come with sensors that collect data at set intervals, which can later be analyzed for trends or anomalies. These devices can be standalone units or connected to a computer for real-time monitoring. Many data loggers store information on internal memory, while others can transmit data wirelessly to a central system. Their versatility and accuracy make them essential tools for researchers and industries alike.
