Hello,
I am attempting to put together a circuit for a MEMS gas sensor which requires a short pulse (2 ms) of 3.0 V followed by <998 ms of no voltage. I would normally try and program this through the micro controller, but 2 ms is too short a time for me to do so. The circuit diagram for this sensor indicates using a transistor to accomplish this, but I haven't the first clue how to go about implementing that. I've posted the circuit diagram below. What would be advisable as a solution? Thanks in advance.
