Sensing techniques refer to methods used to detect and measure physical properties or changes in the environment. These techniques can include various technologies such as sensors, cameras, and microphones, which convert physical phenomena like light, sound, or temperature into signals that can be analyzed. These methods are widely used in fields like robotics, environmental monitoring, and healthcare. For example, temperature sensors can monitor climate conditions, while biometric sensors can track vital signs in patients. By utilizing these techniques, we can gather valuable data to make informed decisions and improve systems.
