This document presents the FCC RF exposure evaluation for the ER-TYSQ water sensor. The evaluation is based on KDB 447498 D01 General RF Exposure Guidance v06, which outlines the test exclusion thresholds for 1-g and 10-g SAR at test separation distances of ≤50 mm. The formula used to determine the exclusion threshold is provided, along with the definitions of each variable.
The test results show the frequency, output power, tune-up power, maximum tune-up power, minimum test separation distance, and the resulting power density. The results indicate that the power density is below the limit, and the SAR test exclusion criteria are met. The conducted power was measured and is detailed in test report HK2504232091-E. The antenna gain is 2.21dBi. The minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 2.48 which is≤ 3, RF Exposure testing is not required.
