STMicro STHS34PF80 IR sensor for motion and presence detection aims to replace PIR sensors

STMicro STHS34PF80 IR sensor

STMicro STHS34PF80 is a new IR sensor designed for IoT and Smart Home devices requiring motion and/or presence detection that offers an alternative to traditional passive infrared (PIR) sensors and is mostly useful for building automation. The latest IR sensor from STMicro contains thermal transistors (MOSFETs) that can not only detect motion but also stationary objects, something that’s not feasible with conventional PIR detectors that require motion for object detection. The company further adds that PIR sensors need a Fresnel lens to sense moving objects, but the STHS34PF80 detector does not require a lens and as a result, enables much smaller designs. STHS34PF80 key features and specifications: Range up to 4 meters without lens for objects measuring 70 x 25 cm² Integrated silicon IR filter IR sensitivity – 2000 LSB/°C RMS noise – 25 LSBrms Operating wavelength – 5 µm to 20 µm Local temperature sensor accuracy – ±0.3 °C […]

FCC and NIST unveils the Cyber Trust Mark, a voluntary US IoT security label

Cyber Trust Mark

Representatives of the Federal Communications Commission (FCC) and the National Institute of Standards and Technology (NIST) have recently unveiled a U.S. national IoT security label at the White House called the “U.S. Cyber Trust Mark” to inform consumers about the security, safety, and privacy of a specific IoT and Smart Home device. IoT security has been a problem for years with routers shipping with telnet enabled with default usernames and passwords, vulnerabilities in SDKs, unencrypted passwords transmitted over the network, millions of devices with older microcontrollers without built-in hardware security features, etc… There have been industry efforts to solve this such as the Arm PSA initiative, as well as regulations to prevent default usernames/passwords in new devices, but nothing about IoT security that can help a consumer find out if a device is supposed to be secure or not. The Cyber Trust Mark is supposed to address this issue. The […]

NEWRACOM NRC7394 WiFi HaLow SoC delivers higher power efficiency and cost-effectiveness

Low cost WiFi Halow SoC

NEWRACOM has just introduced the NRC7394 Wi-Fi HaLow Arm Cortex-M3 SoC with higher power efficiency and lower cost than the previous generation NRC7292 Cortex-M3/M0 HaLow SoC and available in a 6x6mm package. I first wrote about the 802.11ah standard in 2014. Also known as the WiFi HaLow (consumers name), it operates in the 900 MHz band, offers a longer range and lower power consumption for items like IP cameras, and the first products came to market in 2021. I was expecting a flood of new WiFi HaLow devices in 2022 in my year 2021 round-up and it was not exactly a prescient prediction as it never happened. But maybe the new NRC7394 SoC will help make WiFi HaLow devices more popular by lowering the costs and further improving battery life. NEWRACOM NRC7394 key features: CPU – Arm Cortex-M3 core @ 32 MHz for IEEE 802.11ah WLAN and application Connectivity Full […]

zigpy-zboss library makes Nordic Semi nRF52840 Zigbee dongles compatible with Home Assistant

nRF52840 Home Assistant

zigpy-zboss is a Python library that adds support for Nordic Semiconductor nRF52840 modules to zigpy open-source Python Zigbee stack project, as well as other Network Co-Processor radios that run firmware based on ZBOSS Open Initiative (ZOI). This enables integration with compatible Zigbee gateway implementations such as Home Assistant’s ZHA integration component and allows users to directly control Zigbee devices from a wide range of manufacturers such as IKEA, Philips Hue, SmartSung SmartThings, ITEAD SONOFF, Xiaomi Aqara, and others. Home Assistant’s ZHA integration already worked with Zigbee dongles based on Silicon Labs Mighty Gecko EFR32MG21 or Texas Instruments CC2652P microcontrollers, but now it’s possible to use nRF52840 dongles and development as Zigbee Coordinators thanks to the zigpy-zboss library.   The zigpy-zboss ZBOSS radio library for zigpy source code and resources can be found on GitHub, but note that this is still an unofficial and experimental port, so testers need to manually […]
