Hi, I am facing issue with the IR sensor FC 51 in measuring distance of obstacle.

Hi, @dikshakumarikangra07 Welcome to the forum. [image] How to get the best out of this forum IDE 1.x See also FAQ - Arduino Forum for general rules on forum behaviour and etiquette. Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of t…

The IR sensor FC 51 is not suitable for measuring distances to an object. It can only detect the presence or absence of a reflective surface. There is a sensitivity control to adjust how far away the object is sensed, but it is in no way calibrated.

TOF10120 is a "laser" time-of-flight limited to under two meters. [image] TOF10120 Time Of Flight Distance Sensor Instructions for setting up TOF10120 distance sensors in ESPHome.

Yes, Tom, this is a school project. I got my answer.

How can I extend the range of the IR sensor FC 51 and measure the distance?

Hi, And what output do you get as you move an object towards the sensor with the code in post #10? [image] dikshakumarikangra07: float distance = 27.86 * pow(voltage, -1.15); Where did you get this equation, what are the "distance" units? Thanks.. Tom... :grinning: :+1: :coffee: …

Hi, @dikshakumarikangra07
Welcome to the forum.

What is the issue?
What model Arduino are you using?

Have you got any code?

Can you please tell us your electronics, programming, arduino, hardware experience?

Is this a school/college/university project?

Thanks.. Tom...
