Infineon PASCO2V15 CO2 sensor achieves ±50 ppm accuracy with built-in microphone and IR emitter

PASCO2V15 XENSIV PAS CO2 Sensor

Infineon’s PASCO2V15 CO2 sensor is a compact and precise carbon dioxide sensor that uses photoacoustic spectroscopy (PAS) leveraging its built-in microphone and IR emitter to detect CO2 levels by measuring pressure changes caused by the absorption of infrared light by CO2 molecules. The sensor is highly precise (±50 ppm ±5%) and can cover a wide range (0 to 32,000 ppm). it also includes features like pressure compensation and automatic baseline offset correction for reliability. With its small size and low power consumption, the PASCO2V15 can be integrated into HVAC systems, room controllers, smart thermostats, air purifiers, and other devices to optimize ventilation and improve energy efficiency. PASCO2V15 CO2 sensor specifications Sensor technology  – Photoacoustic Spectroscopy (PAS) with Non-Dispersive Infrared (NDIR) principles Gas measured – Carbon Dioxide (CO2) Measurement range – 0 to 32,000 ppm Accuracy – ± (50 ppm +5%) of reading between 400 ppm and 3000 ppm Output Interfaces […]

SONOFF ZBMINIR2 tiny Zigbee 3.0 switch also works as a Zigbee router with up to 64 sub-devices

SONOFF ZBMINIR2

SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state. The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs. It also supports external switches (momentary, door, SPDT, and rocker), voice control through Amazon Alexa and Google Home, and like other SONOFF devices is designed to be controlled through the eWelink mobile app by default. SONOFF ZBMINIR2 specifications: MCU – Unspecified – Potentially the same […]

WiCAN Pro – An ESP32-S3-powered OBD scanner for vehicle diagnostics with Smart Home integration (Crowdfunding)

wican pro

MeatPi Electronics introduced the WiCAN Pro, an ESP32-S3-based OBD scanner, and the successor to WiCAN-OBD. Equipped with an OBD-II interface IC, it provides full support for all legislated OBD-II protocols. It offers compatibility with multiple CAN Bus protocols, including three standard CAN Bus and single-wire CAN Bus. The previous generation WiCAN module came in an OBD or USB-based version. The WiCAN Pro only has an OBD interface, but another significant difference from the previous product is that it features a USB host port. This port can power USB devices up to 1.5 amps at 5 volts and enables capabilities like adding GPS or cellular-based radios, like with meatPi’s ESPNetLink add-on.   WiCAN Pro specifications: Wireless Module – ESP32-S3-WROOM-1-N16R8 SoC – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM Storage – 16 MB flash Wireless – 2.4 GHz WiFi […]
