Excuse me,I am the after graduate student of Taiwan.

I wonder to know that how to measure the power consumption of sensor like DHT11 or MQ-2.

Thank you for answering my question.

It's very mean to me.

Their datasheets will tell you:
If you dont believe the datasheets, you can measure the current (and voltage) to the sensor.
multiply the two reading


Thanks for telling me the information.

It's very helpful.

Excuse me, I have another question.

Is that possible to detect and measure the power consumption of sensors and than transmit the data to
the arduino.

Sorry for asking so many questions.

But I really want to know the knowledge about the arduino and sensor.
