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:

Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
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...
In this blog post i will share the OLED libraries with you, which are written for mikroC compiler and can be used with any other C compiler.
Following are the functions which are currently present.
void OLED_Init( void );
uint8_t OLED_Width( void );
uint8_t OLED_Height( void );

that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
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...

Stencil Types
Important print quality variables include accuracy and smoothness of the stencil aperture sidewalls. Maintaining a proper aspect ratio between stencil width and thickness is important. The recommended aspect ratio (aperture width divided by stencil thickness) is 1.5. This is...

A description of the shape and size of the tool used to create a pad or track. The term comes from...
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
Thank you for reading my blogs.
I came back again ! ;-)
As i gave promise , i came back to continue about class D amplifier and SMPS !
See below , pictures , please :
Think about top photos !
Could you get my mean ?
If yes , good .
If no , no , don't worry ...
Hi Dear All
Thank you for reading my blogs .
As i promised , i came back with more discussions about class D amplifiers and SMPS ( Switch mode power supply) systems :
below you can see 2 picture , one of them a circuit to make PWM ( not SPWM ) and the other the waveforms .

As for any project first thing to make are design considerations. They are what actually makes your project look this way or another. There are quite a few things to consider.
For the first thing I had to decide was the actual porpose of this machine. the answer is that I want to be able to...
Hi everyone. This is the first post in this blog. The blog itself will describe my efforts to build a CNC Mill.

Hi Dear All
When i learned the class D amplifier , i was , 16 years old . and the problem was that i tired from dissipative amplifiers such as Class AB and C . ( and all of the times i like learning new things )
So , i read many articles from big companies , such as International Rectifier ...

It might not be obvious to the casual user, but LTspice can be used to work with WAV files. This is a feature that most power users are well aware of but might not be obvious to new users.
Basically, LTspice allows the inclusion of WAV files in the simulation by the way of independent voltage...

For those compilers that do not have a built-in function for swapping a byte's nibbles, a simple user function can be created:
unsigned char SwapNibbles (unsigned char x)

return ((x >> 4) & 0x0F) | ((x << 4) & 0xF0);
}
And a couple of function call examples:

Getting a solid grasp of static timing analysis in digital circuits can be a very big challenge. It usually takes quite a bit of experience. In my view it’s not covered very well in school, and because of that it’s more difficult for new engineers.
I’ll attempt to cover this topic in depth...
