• •The influence of temperature on the RI sensing performance of a in-line fiber Mach-Zehnder interferometer was investigated.•The conclusion was demonstrated in both simulation and experiment.•It shows that the temperature variation lead to a RI deviation in the RI measurement but do not affect the RI sensitivity.•A RI correction was given to eliminate the RI deviation in the measurement. The influence of temperature on a refractive index (RI) sensor based on an in-line fiber Mach-Zehnder interferometer (MZI) was investigated in both simulation and experiment. The RI sensing performance of the sensor was investigated at different temperature (25–60 °C) over an RI range of 1.33–1.37, and the RI sensitivity of the sensor was around −20.00 nm/RIU at different temperature. The results showed that the temperature variation led to a RI deviation in the RI measurement, but hardly affect the RI sensitivity. To eliminate the RI deviation in the measurement, the RI correction was given.
