Hi. First i'm sorry if my English is not so good as i try :?
I am thinking to make a datalogger with a palm m125. The palm i already have, but now i am with several doubts.
I will need for now 4 channel's, but i was thinking for 5 channel( one more for the future).
1-Channel is to read RPM from a 2-cycle engine and the problem is that the engine goes to 20000 RPM i was think in hall sensor to read the pulses from engine :shock:
2-Channel is to read temperature [0,250]ºC i was thinking in LM35 because is linear but the limit is 150ºC so i need a thermocouple, i think
3-Channel is to read velocity up to 130 km/h i think this one is easy to do
4-Channel this channel is a magnetic sensor to trigger the system
5-Channel is for G-sensor or any other , for now is off.
So i am collecting ideas to put this project on paper and on "ground" all the help that any one could give, are welcome.
Best regards.
