Before this i tried to design the circuit and simulated but failed to get the output. I also faced a problem when using the software ... i could not find the transmitter part and think that part is not available in that software. this is the sensor output range that it should be. http://www.8051projects.net/forum-t13645.html 2009-01-08T09:03:57-08:00 Ajay what have you done till now? http://www.8051projects.net/forum-t13645.html 2009-01-08T09:03:57-08:00 arejar21 sorry..this the link for block diagram.http://rapidshare.com/files/152085452/block_diagram.rar http://www.8051projects.net/forum-t13645.html 2009-01-08T09:03:57-08:00 shyam hey the diagram is not clear can u rar it and then upload the link?? http://www.8051projects.net/forum-t13645.html 2009-01-08T09:03:57-08:00 arejar21 so far i already designed for force sensor circuit..but the output voltage is too small and negative. Furthermore, i'm facing a problem to understand and use the software (beginner).
