could you provide setup vendor ?

I have used the mos sensor MQ135 to measure CO2 , the operation was normal as long as the power came from a usb port of my pc.
Switched to a 9V battery this initially worked well but after a few hours the battery ran out.
Is this normal due to high heater consumption?
