WEBThis chapter presented an overview of sensors with basics, characteristics and different types of sensors. A sensor is a device that receives a signal and converts it into an electrical signal. These sensors are classified on the basis of their applications, cost, accuracy and range.
WEBSensor (e.g., thermometer) a device that detects/measures a signal or stimulus. acquires information from the “real world”. Actuator (e.g., heater) a device that generates a signal or stimulus. Typically interested in electronic sensor. convert desired parameter into electrically measurable signal.
WEBBrief descriptions of the sensors are given along with their advantages and disadvantages. A sensor is an electronic device which measures changes in a quantity, for example, voltage, temperature, pressure, and humidity. Classification occurs, therefore, on the basis of the property that is measured by a sensor.
WEBUnit Overview. The following topics will be discussed: What are Sensors? Types of Sensors. Type of micro-sensors. Introduction. A sensor is a device that receives and responds to a signal. The signal could be heat, light, motion, or chemical. A sensor converts the signal into an analog or digital representation of the input signal.

WEBA sensor is a device that converts a physical phenomenon into an electrical signal. As such, sensors represent part of the interface between the physical world and the world of electrical devices, such as computers. The other part of this interface is represented by actuators, which convert electrical signals into physical phenomena.
WEBApr 27, 2012 · Within the healthcare, wellness, and environmental domains, there are a variety of sensing approaches, including microelectromechanical systems (MEMS), optical, mechanical, electrochemical, semiconductor, and biosensing.
WEBThis chapter summarizes the various bases of classification, namely requirement of external signal, types of produced signal, means of detection, conversion phenomenon etc. This chapter also describes the features, implemented techniques, and applications etc of modern sensors.
