I live in NYC too, and recently have often had really off-readings (between 100-200 points off - high and low). These misreadings have been going on with my last previous 2 sensors.
I only use the sensors for 7 days, each. During these 2 weeks, it has been 100+ degrees here, so was wondering, as well whether I've just had bad luck with my recent 2 sensors, or whether it is a heat issue.
I usually don't sweat much, but in the heat I have been. Though none of my sensors have fallen off from the sweat, I can't help but think it still must be affecting the readings.
I have a new sensor on now, and numbers seem to be more accurate, like in the past (rarely, if ever off by more than 50pts.). But the heat spell has broken, and I'm sweating less. So, I can't narrow the possible problems(s) for the resent 2 sensor misreadings.
I would like to avoid a repeat, if the temp. starts going up again. Does anyone have any info.?
Any Ideas of waterproof tape to use to keep the sweat away from the cannolla, etc.?? Or if the heat is just an inherent problem for the sensors I have to deal with, and finger-stick more to double check in the heat.
