vivel.roy2991: can you please tell me how me to implement that.
i mean what type of membrane. what type of accelerometer. and where to fix that accelerometer.
hello friends..
I have one UPS for PC. it will give power for full load up to 30min without any supply power. when i use that power for mobile charging, or some light. Even it has full charge, It will automatically turned off after 5min. can any one tell me the problem.
I have a problem in serial communication between At89s52 micro controllers. I thought to use rs485 for connecting more devices in network. for testing I connect two controller alone.
I assume one as a master and another as slave. If I initiate transmission from master it reaches slave...
ya it was good. can we use piezoelectric principle. because its working is easy to fix threshold level, in order to find maximum stress a man can with stand.
hello friends,
i needed to find the force exerted over a body during boxing. how can i find this force.. i thought one piezoelectric principle. can we use piezoelectric sensors and voltage comparator for this application.
no. i'm asking is there any electronics sensors behind this. like a sensors used for ECG in medicals.

can i use weight sensors for...
hi, i want to know about physical pressure sensors used to calculate the force. i have seen this type in some science channels. they used for testing the energy level of wrestlers. can any one tel me, what type of sensors that is? and how it work?
thanks in advance for your comment.
can any one give some idea about how to design a circuit for range finder using at89c2051 and 40khz ultrasonic sensors.... i have given a sample circuit,

which i found in google. they used atmega... can i use...
ok. what should i do to do this in half duplex mode.

thanks. what should i do to do this in half duplex mode.
i wanna do more than 1km lenth. and i thought some repeater will help to do this, i mean for this much device. and that voltage divider may avoid reflection in network.
