Sounds like what im doing right now but... ran into another problem... See the timer works but keeps generating data over and over at a rapid pace, im trying to keep incoming data at a 5 second interval xD I know maybe it is over the top but I would desire that for my data logging, or should I keep my sensor always on and only take the data that I need at every 5 seconds, because i am guessing in this scenario that my relay is functioning in the same way that my sensor is?
