SX9331WQ
The SX9331WQ is a 5 channel smart capacitive proximity sensor for Smart Human Sensing as well as other demanding proximity and touch applications. It has a unique Smart Human Engine that is able to accurately discriminate between an inanimate object and human body. Operating directly from an input supply voltage of 2.7-3.6V, the SX9331WQ outputs its data via I2C serial bus. The I2C serial communication bus port is compatible with 1.8V host control to report body detection/proximity and to facilitate parameter settings adjustment. Upon proximity detection, the NIRQ output asserts, enabling the user to either determine the relative proximity distance, or simply obtain an indication of detection. The SX9331WQ includes an on-chip auto-calibration controller that regularly performs sensitivity adjustments to maintain peak performance over a wide variation of temperature, humidity and noise environments, providing simplified product development and enhanced performance.

More than 80% of the world’s population, or 6.648 billion people, own a smartphone — and all of them emit a low-level of radio frequency (RF) radiation. In particular, 5G phones are designed with high-performance RF devices and contain an increased number of antennas to support the demand for more reliable connectivity and greater bandwidth.

An independent investigation recently conducted by The Chicago Tribune revealed that some of the most popular cellphones might come with radio frequency (RF) radiation levels well above the legal safety limit. This finding has drawn public attention to cellphone RF safety and also prompted a follow up investigation by the Federal Communications Commission (FCC) in the United States.
