HCSR04 is an Ultrasonic ranging module which consists of a transmitter,receiver and control circuit. It has four pins for VCC, GND, Trigger and Echo.You can easily interface it with micrcontrollers and Arduino boards.
The basic principle of work is:
(1) Using IO trigger for at least 10us high level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level , time of high output IO duration is
the time from sending ultrasonic to returning.
Test distance = (high level time×velocity of sound (340M/S) / 2

Ata ottonto dukkho-jonok !
Ata holo sob kichu ak jaiga theka kena ar ghore boshe thakar mashul !
Believe me ! Ami jantam, apnera atar dam baraben ! Thik tai e holo !
Dam beshi bole kee oporad korsi naki ??
Of course "Nobody is telling anyone to be confine to home, nobody is telling anyone that they must purchase it from TSB. "
YOU DON'T NEED TO REMIND THAT !
NO ONE IS ASKING YOU TO MAKE LESS PROFIT EITHER !
But you must remember that, this kind of attitude (the way you reply to your customers) will be harmful to your business at some point !
" Convenience comes at high price", sai kotha e ami bollam , ar apne tele-begun'e jole uthlen ? !
I am really shocked !!
I also appreciate whenever you lower the price of some products or bring something really good !
But when you say "People working here are much senior to you in age and academic qualification" , I agree on the first part that some of you might be few years senior to me But When You Question My "ACADEMIC QUALIFICATION" DON'T YOU THINK YOU ARE INSULTING ME ?
Do you have any idea about my Academic Qualification ?
For your Information I have completed BSc in EEE (2011)+ worked in a power plant for 2 years as an Assistant Engineer + continuing MSc in University of Dhaka !
Please don't insult your customers, we will of course respect you for your contribution of "Making Things Happen" and providing support for Development Activities in the field of On Hand Electronics, helping young generation to learn properly.
Thank You !
