Sensors are devices that detect and respond to some type of input from the physical environment. They are used to measure and monitor various conditions such as temperature, pressure, humidity, motion, and more.
Sensors are devices that measure physical properties such as temperature, pressure, light, sound, and motion. They are used in a variety of applications, from industrial automation to consumer electronics. Sensors are used to detect and measure changes in the environment, and to provide feedback to control systems.
Sensors can be divided into two main categories: active and passive. Active sensors require an external power source to operate, while passive sensors do not. Active sensors are typically more expensive and complex than passive sensors, but they are also more accurate and reliable.
The most common type of active sensor is the transducer, which converts a physical quantity into an electrical signal. Transducers are used in a variety of applications, from medical imaging to industrial automation. Other types of active sensors include thermocouples, strain gauges, and accelerometers.
Passive sensors do not require an external power source to operate. They rely on the physical property they are measuring to generate a signal. Examples of passive sensors include thermistors, photodiodes, and piezoelectric crystals.
