The word “Transducer” is the collective term used for both Sensors which can be used to sense a wide range of different energy forms such as movement, electrical signals, radiant energy, thermal or magnetic energy etc, and Actuators which can be used to switch voltages or currents.
Input type transducers or sensors, produce a voltage or signal output response which is proportional to the change in the quantity that they are measuring (the stimulus).The type or amount of the output signal depends upon the type of sensor being used. But generally, all types of sensors can be classed as two kinds, either Passive Sensors or Active Sensors.

R Problem 4 (15 points): The output of an infrared distance sensor (with zero output impedance) varies from O to 5 V linearly as the distance of an object from the sensor changes from 0 to 100 cm. The output of the sensor is connected to the input of the circuit shown on the right (where the op amp has supply voltages +2 V and -2 V, and R = 1 ks). If you want this entire system to measure...

You have a sensor that has a maximum output of 25 Volt, and you want to feed this signal intoa data acquisition (DAQ) board with a maximum input in the range 0, +101 Volt. Design a circuit that matches the sensor to your DAQ board with the following design criteria: a) You need to attenuate the input signal by a factor of 2.5 b) The sensor cannot provide any current; therefore you need to make sure not to cause a...
