IR Range Estimator

The IR Range Estimator utility helps you determine if the object you intend to detect with the Si114x proximity and ambient light sensor would be within range, and if the SNR (signal to noise ratio) threshold is high enough to trigger a detection event. To calculate whether or not you have adequate SNR, enter details about your application on the left side, and then view the results on the right side.

Note: The estimation tool is provided as a guideline only. The utility is not meant to be exhaustive nor provide a range estimation for every possible scenario.
