0. Remove/disconnect the power LED. 1. Consider powering the sensor via a GPIO pin that you set high when you want to take a reading rather than connecting it

0. Remove/disconnect the power LED. 1. Consider powering the sensor via a GPIO pin that you set high when you want to take a reading rather than connecting it to the positive rail. 2. Research whether your chip can be easily put into deep-sleep mode (the -01 boards require a jumper wire to be soldered to one of the IC legs which is not super-easy to accomplish).
