Temperature Sensor giving me a very inaccurate reading

i submerged my rov underwater and the temperature reading that i was getting was 56 degrees Celsius. the water isn’t 132 degree Fahrenheit so is there a fix to this problem. BTW im using the fast response temperature penetrator and that is connected to an i2c splitter and that goes to a pixhawk. im using the splitter because have to use the depth sensor too. i dont know if that could affect the signal or not

Hello, will you please save a telemetry log demonstrating the problem and post it here?
