Hi(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to calculate the power required to take a measurement using a sensor. Datasheets do not provide the power requirement for devices (in watts). Can anyone give me any advice on how to find the power requirement using information provided in a typical datasheet? I know I could just use the equation P=IV, but surely it's not that simple.

I'm not sure if it makes a difference, but the sensor will not be used continuously, just one measurement needs to be taken.

Thanks for your help
