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...
In this blog post i will share my Graphical Lcd libraries with you which are written for xc8 compiler in MPLAB-X development environment.
The libraries functions are inspired from mikroC functions and i tried to keep most of the functions similar to the one available in mikroC compiler.
Some...
Find bellow an Android TCP client extension
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...
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.

Moore’s law states that the level of technology and computing power should double every two years, and so far the postulate hasn’t been wrong in more than 50 years. A group of IBM scientists have now managed to develop a data storage technique which allows for information to be stored with as...
I think everyone knows what doppler effect exactly is. I wish to write what I understood about doppler effect intuitively. If you think that I am wrong you can correct me.
Assume that a wave is coming towards you. It's time period is T seconds. Now the frequency that you see will be...

Usually we represent the gain in terms of decibel (db). Have you ever wondered why we are doing like that? I found this while I was reading about Bode plot.
The main reason for working for log is because multiplication becomes addition in log. So this reduces the complexity.
Consider a...
Magnetoresistive Random-Access Memory is a non-volatile computer memory (NVRAM) technology that has been under development since the 1990s. Continued increases in density of existing memory technologies – notably flash RAM and DRAM – kept it in a niche role in the market, but its proponents...
It was a summer vacation time, and then I was a high school student. I came across an unusual book. It said “you can do arithmetic’s at stunning speed without pen and paper” . I began to read the book and felt the magic .it was amazing, I was able to do arithmetic at stunning speed and the...
In electromathematics two important functions play a major role in determining the system response to an arbitrary input. Indeed it's only one function which is called as the Transfer function of the system. From the transfer function of the system we can find out the characteristic equation...
