Smart sensors for personal connected consumer devices
Analog and mixed-signal semiconductor supplier Semtech has announced a line of sensors targeted for the personal connected consumer device market that can differentiate between humans and inanimate objects.

Derived from the term "Person Sensing," the PerSe product family consists of three core product lines: PerSe Connect, PerSe Connect Pro, and PerSe Control. The new sensors, says the company, deliver ground-breaking user experiences in smartphones, laptops, and wearables by intelligently and automatically sensing human presence.

PerSe sensors intelligently sense human presence near the mobile device and other consumer electronics, and enable advanced radio frequency (RF) control when the user is in close proximity. The sensor family's unique smart human sensing feature, ultra-low power, and tiny footprint, says the company, also make it the ideal sensing solution for a wide range of wearable applications such as gesture control and automation.

By leveraging its PerSe technology, says the company, leading consumer electronics manufacturers can now deliver high-quality connectivity in 5G/Wi-Fi 6 with increased RF performance in their smartphones and laptops, while also helping ensure compliance with the worldwide specific absorption rate (SAR) regulations. PerSe is offered as providing best-in-class sensing performance and robust noise immunity allowing original equipment manufacturers (OEMs) and original device manufacturers (ODMs) to design devices with longer detection distance within a smaller sensor area.

The PerSe portfolio includes:

  • PerSe Connect : Enhances connectivity for many of the global smartphones and laptops (5G Sub-6, 4G and Wi-Fi). The sensors help optimize the RF power for best connectivity and help to maintain SAR compliance while delivering a fast wireless experience on these devices.
  • PerSe Connect Pro : First of its kind to provide ultra-high sensing performance for high band 5G mmWave devices in smartphones, laptops and tablets. PerSe Connect Pro enables higher sensing distance to safely manage the increased RF exposure.
  • PerSe Control : Enables smarter control in wearables to improve the user experience. PerSe Control enables human detection, automatic on/off and start/stop response. It also delivers cutting-edge gesture control and response including smart assistant, noise cancellation activation and media player control.
