Giveaway Week 2023 winners announced!

CNX Software’s Giveaway Week 2023 is now over and we’re ready to announce the winners. We offered some of the review samples we tested (or not) in the last year, and like the last two years, we were also joined by RAKwireless who offered two IoT development kits. All items given away are shown in the photo below, minus some accessories, and if you count more than seven you’d be right, as some are kits with multiple items like the GL.iNet GL-S200 Thread Border router which comes with three development boards, and more importantly, we also organized Giveaway Week on CNX Software Thailand for the second year running. We had seven winners on CNX Software: VOIPAC iMX8M industrial development kit – Kraingsak, Thailand TBS7901 mini PCIe DVB-S2X/S2 module – Frank, Singapore RAKWireless WisBlock IoT Starter Kit – Andy, Russia GL.iNet GL-S200 Thread Border router kit – Augustin, Argentina WCH CH583M-R0-1v1 […]

Review of RaZberry 7 Pro Z-Wave Raspberry Pi HAT and Z-Uno2 Z-Wave board

Z-Wave.Me has sent us a couple of Smart Home devices based on Z-Wave technology for review, namely the RaZberry 7 Pro Raspberry Pi HAT and the Z-Uno2 board. The Swiss company has primarily developed Z-Wave products for years and is a member of the Z-Wave Alliance. For those who are concerned about the issues of signal interference in the 2.4GHz range (WiFi, Zigbee, Bluetooth, and Thread), Z-Wave technology is an excellent choice because it operates on a less congested frequency range of 800-900MHz and the technology has been around for more than 20 years, resulting in a wide variety of Z-Wave devices available in the market, and they can work well together across different brands due to a proper certification process which is another advantage when compared to other protocols. The two devices we received are RaZberry 7 Pro, which is a shield that plugs into the 40-pin GPIO header […]

SONOFF SNZB-06P Zigbee human presence sensor is based on a 5.8GHz microwave radar

SONOFF SNZB-06B human presence detection sensor

ITEAD has launched a new Zigbee sensor with the SONOFF SNZB-06P designed to detect human presence using a 5.8GHz microwave radar whose main advantage over a traditional PIR motion sensor is the ability to detect stationary persons since this type of sensor can detect breathing. You’ll need a Zigbee Hub from SONOFF such as the NSPanel Pro or SONOFF iHost, or from other manufacturers, for instance, the Amazon Echo Plus 2nd generation, or simply use a Zigbee USB dongle such as the SONOFF ZBDongle-E connected to a host like a Raspberry Pi. Configuration and control is done through the usual eWelink app for Android or iOS. SONOFF SNZB-06P specifications: MCU – Silicon Labs EFR32MG22 wireless microcontroller Human presence sensor 5.8GHz microwave radar Sensitivity configurable from 2.5 meters to 4 meters Wireless – Zigbee 3.0 (router type) up to 30 meters Misc – Red LED, magnetic base, button Power Supply – […]
