HSM-20G is one of the most common humidity and Temperature sensor. This sensor is fully analog type. The outputs are analog voltages rather than any digital signal.
The datasheet indicates that the output pins need some extra devices with it. here is the connection diagram:

Time Domain Reflectometry is the analysis of conductor lines (interconnects)by sending a pulsed signal into the conductor and then examining the reflection of that pulse. A TDR transmits a short rise time pulse along the conductor. If the conductor is of a uniform impedance and is properly...
Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
There is an ever-increasing demand for wireless broadband applications. This includes wireless HD video streaming, wireless backhaul links, broadband internet access and mass files transfer applications. All of this emphasizes the need for low cost and efficient millimeter-wave (mmWave) systems...
Hello!
I'm an electronics newbie and recently came across an oscillating opamp. I didn't even know that opamps had that problem. Through these forums and numerous online readings, I finally understood what an oscillating opamp is. I found a few others looking for answers to the same question...

Generally people use ISP (In System Programming) when it comes to micro controllers with flash memory.
One of the basic software for such purpose is FLASH MAGIC .
But every single person who has ever used flash magic knows it never works the very first time and the frustration goes on...

HOW TO BUILD "B Battery" basics on "B battery" eliminators and run vintage tube gear
There are many ways to get high voltage for projects or vintage radios/amps and tube gear. Quick searches
usually lead to great but semi-complex and expensive to build circuits for this purpose. To...

Ansys HFSS normally uses the scattering parameters convergence as a termination condition. Although, this does not necessarily mean that the solution converged everywhere, it is a fast and efficient criterion.
Few days ago, I was running the built in optimizer in HFSS searching for the...

This is actually a continuation of my blog entry https://www.edaboard.com/blog/1628/ where I have used C language routine. Now its the time to use Assembly Language for PIC. The Code is tested on PIC16F84A with 4MHz crystal. Compiler used MCS-51 under M-IDE Studio.
The associated program...
In this blog entry I will show you how to use a 74HC595 to expand I/O pins using only 3 I/O pins of a microcontroller. The program is tested on a 16F876A at 20MHz.
The associated program shows how to transfer a byte data serially to the 74HC595 and then sets the output accordingly...
I read a small portion on Maxwell's equations in the second part of this book and I say that I have never read anything more interesting than this. It's really awesome by the way. The author is a well known personality. He is the Nobel Prize Winner Richard Feynman, who specialized in quantum...
Most microwave hardware is specified to run in a fifty ohm system. Why was this standard chosen?
50 ohms is a great compromise between power handling and low loss, for air-dielectric coax.
The arithmetic mean between 30 ohms (best power handling) and 77 ohms (lowest loss) is 53.5, the...
1.) seperate the power grounds, signal grounds, analog grounds, digital grounds, control grounds
2.) Keep inputs and outputs seperated and isolate to prevent oscillations
3.) Oscillation can happen from the inverting input and non-ineverting input of op-amps, coupling between parallel signal...
As is well known, solderability is very important for the printed circuit boards, we must do solderability test of each batch PCB we made. In this way we can inspect the weldability of the PCB before we go ahead the assembly process, much helpful for SMT.
Today we are going to discuss the...
Dear All
Hi
I came back again , with some good things !
And if you see i don't write all things at one , blog , the reason is that i want you think about things that i write carefully .
Before that , let me appreciate from "LvW" and "FvM " and "syncopator " , because of their friendly helps...
PRACTICAL CONSIDERATIONS
All this while, we’ve talked about the software side of things when dealing with the ADC. Now, it’s time to talk about the hardware side of things.
We’ve considered many situations in the discussions above. But not all of them can be used in your circuits.
One...
SEQUENTIAL STEPS IN ANALOGUE TO DIGITAL CONVERSION USING THE INTERNAL ADC
So, here are the steps to configure the ADC and carry out the conversion:
• Decide which pins need to be analogue, which pins need to be digital and which (if any) need to be configured as reference pins.
• Select the...
ADC pinout of PIC 16F877A
PIC16F877A has 8 ADC input channels. That means that 8 pins are multiplexed (connected) to the PIC ADC module. So, you can use the ADC module to convert analogue input from 8 inputs. PIC16F877A cannot do the conversions simultaneously, so it must be done one by...
Right/Left Justification continued
When you have a 10-bit number (range is 0 to 1023), if you divide the number by 4, you effectively just converted the 10-bit number to an 8-bit number. The new range is 0 to 255.
You should already know that bit-shifting a number to the right once is...
Acquisition Time
Before an analogue to digital conversion is to be started, a small amount of time must be allowed for the holding capacitor of the PIC ADC module to fully charge to the input level. This is how the ADC works and unless this minimum time is allowed, the ADC will give an...
Introduction
The ADC is used to convert an analogue input signal (an analogue voltage within a specific range) to a corresponding digital data that can be processed and used by the PIC. The PIC, without the conversion to digital, can do almost nothing with an analogue input (unless you use...

The maximum analog voltage you can give to your PIC (directly, without any divider) is 5V. So whatever analog signal you are trying to measure, make sure that the i/p volt to that pin should not exceed beyond 5V. If you want to measure voltage more than 5V, you should use resistor voltage...
Hi All
I came back again , as i promised .
Thanks for reading my blogs.
Well , the PWM ( pulse width modulation ) consist from DC component ( DC as message ) and High frequency components .
And SPWM ( sinusoidal pulse width modulation ) consist from message signal and high frequency...
There is a fact to mention about the resolution of the A/D converter. Since the converter converts the signals, it takes a certain time. The conversion time of the low resolution A/D takes less time than the conversion time of the high resolution A/D. You have to consider carefully : if you...
Hello,
finally I've got time to write some thing. Still going on design considerations about construction. So the time came to decide materials and type of construction. For a 3 axis cnc your workpiece needs to move in 3 axes perpendicular to each other marked as X, Y and Z. I'll take the...
Hi dear All

If yes , good .
If no , no , don't worry ...
Hi Dear All
