สรุป	Sensor data collection uses physical or digital instruments to automatically capture quantitative measurements from the environment, human bodies, or machines over time. Common sensors measure temperature, motion, heart rate, location, light, sound, or chemical properties. Because the recording is automated and continuous, the method can produce high-frequency datasets with minimal researcher burden, making it central to IoT, environmental monitoring, wearable research, and behavioral studies.	Field notes are detailed written records created by researchers during or immediately after direct observation in a naturalistic setting. They capture what is seen, heard, and experienced — including behaviors, interactions, physical environments, and the researcher's own analytic impressions — forming the primary data source for ethnographic and observational studies.
