A gas sensor system is for use in, or in the vicinity of, a toilet, for detecting a target gas. A gas sensor detects a concentration of at least the target gas and a further, reference, gas which is received from a controlled gas release device. These concentrations are processed to obtain a concentration of the target gas relative to the concentration of the further gas by combining a change in the detected concentration of the target gas, a change in the detected concentration of the further gas, the sensitivity of the gas sensor system to the target gas and the sensitivity of the gas sensor system to the further gas. This approach avoids the need for extensive calibration operations to tune the sensor response to the environment in which it is used.
