Wow, just as I said earlier, if you got nothing constructive to say then dont.....and if your thinking suggesting a dif MCU is constructive, you yourself should know, if in fact you are an engineer, that a systen desiogn is not alwasy strictly bounded by best hardware for the job, as long as the hardware is adequate and the MANY other constraints and criteria are met....the HC12 was not choosen based strcitly on its mardware itself, but rather its architechture, interoperability, and common instruction set, as well as the fact that the particular flavour of HC12 we are using was a cheap, nicely sized portable eval board with all the hardware, mem, and compopnents we needed.....its a ground up build and design, and since im familiar wiht that families instructions et the assembler coding would be done failry quickly and easily.....

So laugh away, you perhaps didnt ask me to explain my project, but when you insinuated that what i stated earlier about checking and cleaning the sensor didnt make sense, i figured, since you were clearly trolling me, and wouldnt understand what i was trying to sayu unless i educated you on said subject I simply had to......otherwise im sure i woulda been met wiht many of the same sort of one line comments like "doesnt make sense".....

Grow up......like i said earlier if you cant answer my question, stay outta the convo....if you dont understand something then try and learn about ti wihtout being an ass...
