Power supply for Wind sensor Rev P
Posted: Fri Aug 28, 2020 8:46 am
Hi Paul, I have ordered another Wind sensor Rev P from Jeelabs.
I would appreciate your advice on why I should not use a step up voltage to power the wind sensor? I am trying to develop a logger to leave in a cave for a week or so to monitor the draught (wind) from various locations, the speed and direction will depend on both outside temperature and atmospheric pressure. I obviously wanted to keep the unit small and didn't want to take a large 12V battery into the cave. I had originally thought I would use 4 x 1.5 (AA) batteries (6V) and then use the POLOLU-2117-UW Converter step up to 12V. The idea was to set the logger to record wind speed using the Rev P and temperature and atmospheric pressure using a BME280 every hour or so. What are the issues with using this setup? You were certain that the step up voltage unit was one of the reasons I was getting an elevated temperature (temp pin) on the previous Wind sensor.
