Amplify uV from Sensors to mV for uC

Amplify uV from Sensors to mV levels for A/D Converters, which in turn may drive a display or connect to a uC means MicroController.

Now there is unicode I can write μC. Now we will break into small html lesson, paste this as html or put it in the source… μ .. you get this… μ .More such neat tricks can be learnt at Entities for Symbols and Greek Letters. I know this is a tough lesson like math, but you better get used to this. (I had to fake this tutor, i have a wysiwyg blogging client which takes unicode characters, this wordpress also set unicode, try your experiments with a NoteTab and one old and one new browser for learning better, i finally set this post by disabling the wp rtf editor and manually typing in μ )

I shall still use uC till Touch-It Virtual Keyboard comes with a Pop-Out Greek Symbol Plate in the free version. I have my own human interface and memory limitation. I am like a 8086 based nobody’s computer in a Penta-Core 5 Ghz Fiber-Computing World, add a 5 Teral Byte HDD. I am Obsolete, i am Legacy. But i have a right to Promote my Worn Out JPEGs.

Now getting back to Bizness, the inputs from the world we interact are analog, A uV level from a Strain Gauge to measure Weight/Pressure; mV from a K Type Temperature Sensor or mV from LVDT Displacement Transducer to Gauge measure linear displacement. All these Low voltage/current, AC/DC need some signal conditioning and special construction – FOR – Amplification, Attenuation, Noise/Pickup Immunity/Rejection, Linearizion, Isolation and Transmission (long wire/wireless).

This means take a small signal sample in the best possible way. The Sensor/Transducer shape and sensing/converting element/technology is chosen/developed. This low mV/uV is then Amplified/Cleaned and Transmitted.Some steps like linearizion can be done by software not all steps. Now we have a nice 0-10 V or 4-20 mA Signal which any A/D with process enthusiastically. The Digital signal will be eagerly processed by a uC with firmware, without batting a eyelid or like the kids say “look no hands” (then its plaster of paris for a few weeks).

I cant do better than this, if you still don’t understand you are destined to become a Hippie. You will be eternally free from work. Lucky Guys. BUT better to be like Ludens.
