How do you use a hall effect sensor to act as a trigger to start the aqusition of data ?

[Paul Briozzo]

On a 4 stroke engine, a hall effect sensor acts as a trigger to instigate the aquisition of data. Data is recorded from a pressure transducer on both the compression and exhaust cycle.

2. What kind of signal does your hall effect sensor output?
3. What have you tried?
