Telemetry is the science and technology of remotely gathering and recording data from distant sources. It involves the collection of measurements and other data from sensors and transmitting it to monitoring and control stations for analysis. Telemetry is commonly used in various fields such as medicine, environmental monitoring, aerospace, and telecommunications to monitor and record data from inaccessible or hazardous locations. It is an essential tool in research and monitoring applications where real-time data collection and analysis are required.
