Power supply
The device uses a Li-Ion rechargeable battery of 7.4 V/3400 mAh that has to be charged with the
12 V/1.5 A charger provided. The charging process can increase the temperature inside the
device and affect the temperature measurement.
The battery life depends on the configuration of the different sensors. It is recommended to set
the same sampling time value for measuring the temperature, humidity and pressure and a higher
sampling time value for the CO

measurement. The recommended configurations and the
estimate battery lives are:
