Classification: CPC G  H | IPC G  H

Claim 7:
8. A gas concentration detection device comprising:
a gas concentration sensor having a gas sensor element that outputs an electric signal according to a gas concentration and a heater that heats the gas sensor element;
a heater controller controlling energization and de-energization of the heater;
a sensor controller having an AD converter AD-converting the electric signal from an analog signal to a digital signal in synchronization with a sampling clock and detecting the gas concentration based on an output signal of the AD converter;
a timing adjuster shifting a switching timing of energization control from a conversion timing at which the AD converter performs the AD conversion;
a first processor located in the heater controller;
a first non-transitory computer-readable storage medium located in the heater controller;
a second processor located in the sensor controller; and
a second non-transitory computer-readable storage medium located in the sensor controller.
