I want to use gas flow meter. I checked for some sensors which have given measurement in ml/min and some has in ml/min.
I tried to convert the ml/min to m/s on google but got the result in m3/s.
I am not sure about the flow measurement and units used in the datasheets.
Is there any explanation...
Hey, I'm new to electronics, and for one of my projects, I'm supposed to design an Ultrasonic Rangefinder using Analog components only!
The components include the 555 timers, SN74HC chips (specifically the 4 bit counter), 7 segment display and etc.
Most of the guides I have found online use an...
I'm working with a distance sensor that gives erratic readings when an object is <2". Here's a plot of MCU ADC counts (orange) and voltage input to ADC (blue).
My first thought is to monitor the dv/dt after we cross the 2" threshold and ignore anything that doesn't have a linear increasing...
I am working on an ultrasonic sensor for occupancy sensing. This device would drive an LED based on movement, and I was wondering if detection could be achieved the following way
Where the sensors and the moving person lie in opposite sides of the wall, and the ultrasonic waves would...
I have a several decades old analog multimeter, which works fine except that the needle stops at slightly different position if the movement goes up, than if it goes down.
As an example. If I probe 10 volts DC (12 V scale), the meter stops at aprox 9 V.
If I change to 3 V scale...
I am using a Texas Instruments Microcontroller (TMS320F28335), I would like to read the analog value from circuit output to be read by the microcontroller using the ADC pins. Please help me in how to do this.
I'm running into some problems designing a 10MHz 8th order sallen-key butterworth lowpass filter.
My requirements are:
cornerfrequency f_c = 10 MHz
max passband gain of 0.5dB
filterorder of 8
available components: resistors, capacitors, op-amps
What I have tried so far:
Regarding CMOS analog IC layout, what are differences between DRC, DFM and DFR?
What I understood during research:
- DRC (Design Rule Check)
checks if a laid out block follows technology rules what ensures dimensional precision and electrical parameters
- DFM (Design For Manufacturing)...
I am working on something similar and would appreciate if you could drop the vi.
Moderator Edit: Thread split off from this:
I am using TE Connectivity Right Angle 50Ω PCB Mount Fitting BNC Connector for signal output in a PCB Board.
It contains 2 Pins. Is Pin 1 for Signal and Pin 2 for ground?
Also, do I need to add any protectors(EMC, Etc...) inboard for this.
Thanks in advance
Hey guys, I'm studying electrical engineering technology and the Coronavirus turned my capstone project into a research paper. My assignment is on PLC's, which we have covered the basics of, but I still know little about how they operate. Here is the prompt:
"Research the ability of PLC's to...
Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors.
I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...
Hi there to you all, I need some help with a troubleshooting/ repair.
I have an analog/digital oscilloscope Hameg HM1500, it has some RTC problem, it presents a partial sweep.
I think is the horizontal circuit, that's either missing a voltage or there is some faulty component.
The only problem...
I made a circuit to demonstrate the work of a 555 and a constant current regulator and wanted to add triangle wave input. I've done that by integrating the output of a 555 timer, and at the node 'tri' I do get the desired triangle wave of ~ +-8V. Since I want the the voltage positive at all...
as I want to calculate the transfer function of circuit that is meant to generate source current using an Op amp as control loop, I need the gm and r0 of the mosfet(to determine the transfer function of the Op amp current source with nMOSFET) here is the picture of MOSFET with showed parameters...
i am referring one opamp based design (designed by friend of mine)where two op amps are used. one in inverting configuration and other one is in non-inverting configuration.
i am bit confused what would be the purpose of using two op amps together?
here is attached schematic. (Here R4 is...
Curently i have a Tension Compression Load cells(attached datasheet) connected to a Electronic control system which Supply's voltage and calculate the force. Right now i need to send the raw data of the load cell to another complete diferent application.
Is there any interface...
Hey, so I've got to build the circuit to output the signal specified below I've currently got an Arduino UNO and I have written the code to output this. however, I can only put out 5v from my Arduino and the circuit requires 12V and 10V output, being able to switch between12 and 0v incredibly...
I have built an op-amp series pass voltage regulator, whose output is inputted into an analog-to-digital converter (ADC0804). The ADC's output is connected to a CoolRunner II CPLD Starter Board. This output corresponds to a value on a look-up table, which determines what value would be displayed...
