Sensor Wire Length

[davidliles]

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.

I2C will work reliably at 1 meter and 100 Kbaud. The distance increases as the speed decreases; i.e., 10 meters at 10 Kbaud.

Thank you for the reply, but please forgive my ignorance... can you explain how the different Kbaud values might impact the sensor?
