2.5 Loading effects. The ratings of a piezoelectric sensor indicate that at a certain stimulus the sensor provides an output of 150 V at no load. The short-circuit current of the sensor is measured and found to be 10 micro(A) (this is done by shorting the output through a current meter). To measure the output voltage of the sensor, a voltmeter with an internal impedance of 10 Mega(ohm) is connected across the sensor. a. Calculate the actual reading of the...

4) A paddle wheel flow sensor that uses hall-effect sensors is used to measure the flow of a fluid and shown in Figure 3. The CPR of the hall-effect sensor is 16 however the maximum flow rate resolution should be 512 pulses. The maximum rate of flow relates to 4 rounds per second of the paddle wheel. The output from the hall-effect sensor is a 5O% square wave -sv to +SV. Develop a design (mechanical and electrical) that provides a...

Liquid Level 1. You are using a 1 turn rotatory potentiometer to design a level sensor to measure liquid level on a tank. The total resistance of the potentiometer R = 10K and the output voltage that is measured by an Arduino is IV. Find the angle of turned in the potentiometer as well as the height of liquid level in the tank. 2. A platinum resistance coil is to be used as a temperature sensor (Rthermal) and has a...

I want to design a microchannel which incorporates a biological sensor. To work, the sensing element must be exposed to enough analyte to reach its detection threshold. This sensor has a detection threshold of 0.1 micrograms of cocaine. My sample contains cocaine at a concentration of 100 nM. Due to size constraints of the chip and sensor, the channel must be 1 mm long. If I want to determine if this sample has cocaine within 20 minutes, what is the...
