is it better to use gpio pins to on/off the stts751 sensor rather than putting it into standby mode for saving power?

I am using the stts751 temp sensor to monitor temp at 5-30 min of intervals. I was wondering instead of using standby mode to save power consumption can I manually on/off the VDD pin to save power consumption? will there be any negative effect on the sensor?

Hi @RSiro.1​ ,

I would prefer the standby mode, but you can of course turn it off and on when you need.

Please note however that, before starting a new acquisition (i.e. after a power off cycle), you should wait till the POR ends (few milliseconds), and you have to configure again the device registers (if you have custom settings), since they are written in volatile memory.
