hello everyone,
I dont have very good chemistry back ground since i have left it 3years ago. I want to know the relation btw concentration and mole fraction. Allow me to explain the problem.
Consider that you are given a one cubic big box consisting of Nitrogen gas in it initially. It is...
why dont you try msp430 series... ? atmega basic ones doesnt have the feature. you will hav to select the IC among many. however in msp430 which is basically for small signals can do you job brilliantly. (it can convert of the order mV or less)
configure pin1.1 as interrupt pin. u can do it.. initialise adc in main function. after that when interrupt occurs, just enable the adc inside the interrupt. it wil work. however i would like to ask one question, why do u want the sampling to start after input is reached? cant it be before? this...
a voltage divider circuit( potential divider) is one of the best option. create a voltage divider circuit and tap the voltage across the needed end. while making a voltage divider circuit make sure u use a preset(or Pot) as one resistor. by doing so u can control the sensitivity of measurement.
use timer option in 8051. when the firing angle(time here) reaches change the output of a pin. the pin should be connected to gate point of TRIAC. all changes u r supposed to do in timer and its count. the complete control u can achieve with it.
have you downloaded sample codes? use single channel continous mode for fetching the input from the device. default sampling rate would do the job. dont give any reference for ADC. I guess G2131 has 10 bit adc. So the sampled output will be in ADC10MEM0. collect the data from there. and write...
design a CE amplifier from 547. This wil give you necessary voltage gain. Darlington pair transistor you can use it as current gain. depending on what volume you req design the circuit with resistor. you have cascade the two. first voltage amplification, then current or vice versa. However while...
To KSHATRIYA: if you have peak voltage of 300mV, then its not possible to get a multiplication factor of 100. The reason is simple. even though in calculation you get 100 or more, the opamp which you use just goes to saturation. You have to use an opamp which has the voltage rating of 60-60V to...
what type of input signal you are giving? i mean voltage ranges?
give the inverse input (if its square wave) directly to ext interrupt pin or counter. write program accordingly.
you can also do using ADC.
