It works on the principle of changing resistance (i.e. rheostat). As the level changes the moveable arm of the sensor moves which cause the resistance to change. This change in resistance is applied to the input of ADC. http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 sunitha how to operate plz.......give detail...... http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 abbas1707 ok first get an old fuel guage of a car. u can get it from some shop which deals with spare parts of cars.try to understand its principle of working...check this out http://auto.howstuffworks.com/fuel-gauge.htm you have to use only the sending unit other things will be done by micrcontroller.tell us in case of confusion http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 sunitha thanku sir if any doudt ill ask u..........sir tell me some more sensors which are simplesir im instrumentation so......im implementing this home atomation over internet to industrial atomation so help me out.......but thanku very much 4 helping....... http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 sunitha ajay sir tell me program to read data by this sever......and show in both the places http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 Ajay sunitha wrote ...ajay sir tell me program to read data by this sever......and show in both the places you mean you want to write your own application based on this? and you want to know how to write code for this software? hope i am getting right... http://www.8051projects.net/forum-t5071.html 2009-01-07T22:30:00-08:00 Ajay can you tell me how other devices are connected in your project.
