it is up to 400 ma during startup or sending data (in very short 100 ms bursts)
but this shouldn't be a problem when powered via 5v, unless you have some very crappy power supply (though even with 1$ chinese ones it is fine)
only the CO2 sensor would not report data if the voltage drops below 4.6v, but then still, the device would boot, and would send the RUNTIME value
