Sensor Wire Length

I have a VL53L1X Time of Flight sensor that I would like to use to monitor cistern water levels and then control a pump relay to fill the cistern as needed. What I'm trying to find out is how long of a wire run can I have from the controller to the sensor and still have accurate readings. If necessary, I could run a power source to the cistern area and locate the controller there, but I would prefer to have the controller in the mechanical room where the pump relay will be located.
