Air Lab is a portable Wi-Fi & Bluetooth LE air quality monitor with an e-paper touchscreen display (Crowdfunding)

Networked Artifacts’ Air Lab is a portable air quality monitor based on ESP32-S3 Wi-Fi & Bluetooth LE wireless SoC, equipped with an e-paper touchscreen display, and plenty of sensors to measure CO2, temperature, relative humidity, air pollutants (VOC, NOx), and atmospheric pressure. The Air Lab ships with a rechargeable 1,500 mAh battery that will be good for about 21 days on a charge in passive mode (taking measurements every minute), and you can also power it over its USB-C ports. It includes a debug port for people wanting to change the firmware, and a GPIO header to connect additional sensors if required. Data can be visualized on the e-paper display or transmitted over BLE or MQTT for integration with Home Assistant. The company also provides a CSV export function and a web-based dashboard for data visualization. Air Lab specifications: Main module – ESP32-S3 module with PCB antenna for 2.4GHz WiFi […]

SPARK Microsystems SR1120 UWB ultra-low-power transceiver delivers up to 41 Mbps throughput

SPARK Microsystems SR1120 is the company’s second-generation ultra-wideband (UWB) wireless transceiver capable of up to 41 Mbps throughput at ultra-low power and up to 100 times lower power ranging than UWB competitors. The Canadian company also highlights the outperformance of their UWB solution over Bluetooth with the new SR1120 offering 40 times higher data rates than Bluetooth chips, while consuming 25 times less power than Bluetooth and offering 60 times lower latency. However, readers should note that Bluetooth LE is supposed to support up to 2 Mbps, so it should (only) be up to about 20 times faster, and Bluetooth HDT is coming soon with data rates of up to 7.5 Mbps to further narrow the gap. SPARK SR1120 key features and specifications: Compliant with the upcoming IEEE 802.15.4ab low-energy UWB PHY standard Dynamically reconfigurable UWB spectrum 6.2–9.5 GHz band Up to 3 dBm TX power RX sensitivity of -81 […]
