SONOFF SNZB-01P/SNZB-02P Review – Zigbee wireless switch and temperature & humidity sensor tested with Home Assistant

SONOFF SNZB-01P & SNZB-02P Zigbee Review Home Assistant

SONOFF launched their 1st gen Zigbee product about a few years ago, and SONOFF have finally started to upgrade their Zigbee devices, and we received two Zigbee 3.0 devices from SONOFF for review, namely the SNZB-01P wireless switch and the SNZB-02P temperature and humidity Sensor. In a nutshell, their appearance looks more modern, with a round shape compared to the rectangular design of the previous models. Importantly, they are sturdier than before, and the battery capacity has increased almost 2x. As we anticipated, they can be used with other Zigbee Hubs from different brands as well. The main application used with both devices is still, of course, eWeLink, which many people are familiar with (a Zigbee Bridge Hub/Bridge is required). However, this review will focus more on the popular app called Home Assistant, which is widely used globally. SNZB-01P wireless switch After trying it out for a while and comparing […]

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 […]
