  • I've been testing these out, and it appears that the power consumption is much higher than advertised. It says in the description that it draws 4mA @ 5V, however I am consuming 15mA @5V, 13-14mA @3.3V, which is much higher than expected. The sensor is worn during this, so I don't think it's from amplifier saturation. This happens consistently for long periods of time, so I don't think it's a fluke, and I just tested it on a brand-new, freshly set up sensor, so I don't think it's the sensor itself.

    Is there something I'm doing wrong, or is this normal? This is for a battery-powered application, so it's important that it is as low power as possible.
