NXP Trimension SR250 short-range UWB radar supports secure ranging for Smart Homes and Industrial IoT

NXP Semiconductors has recently introduced Trimension SR250 UWB radar, which NXP is calling the industry’s first single-chip solution that combines on-chip processing with short-range ultra-wideband (UWB) radar and secure UWB ranging. Operating at 6-8.5 GHz, the SR250 supports features like 3D angle-of-arrival (AoA), time difference of arrival (TDOA), and time of flight (ToF) measurements accurate to within ±5 cm. The integrated on-chip radar processing reduces power consumption, which increases efficiency and it can work with AI/ML algorithms on host processors like NXP’s i.MX, RW61x, and MCX families. The SR250 is supported by firmware, middleware, and sample applications, simplifying development and deployment. Applications for this device include smart home automation (e.g., turning devices on/off based on presence), secure access, and safety monitoring, as well as industrial uses such as worker tracking, collision avoidance, and danger zone detection. Trimension SR250 UWB radar specification 3D secure ranging Fully interoperable with IEEE 802.15.4z HRP […]

SparkFun’s $125 “Indoor Air Quality Combo Sensor” combines the SCD41 and SEN55 environmental sensors

SparkFun has released a new air quality multi-sensor board, the Indoor Air Quality Combo Sensor, which integrates the SCD41 and SEN55 sensors from Sensirion for measuring carbon dioxide, volatile organic compounds (VOCs), particulate matter, relative humidity, and temperature. The air quality multi-sensor board simplifies power management for the two sensors via onboard DC voltage conversion and allows a single Qwiic connection for power and communication. It features two Qwiic connectors and a 0.1”-space through-hole header for I2C and power. The board is not a complete solution for indoor air quality monitoring. It has to be connected to a Qwiic-enabled microcontroller such as SparkFun Thing Plus Matter, DataLogger IoT, and the ESP32 Qwiic Pro Mini. Users can install the required Arduino libraries — the Arduino Core library, Sensirion I2C SEN5x, and SparkFun SCD4x — either via the Arduino library manager or directly from SparkFun. The device is open-source, with hardware files, […]

Renesas RRH62000 multi-sensor indoor air quality monitoring module features particle, VOC, and gas sensors

Renesas Electronics has introduced the RRH62000, a compact multi-sensor module for indoor air quality monitoring. It integrates particle detection, VOC, and gas sensing with an onboard Renesas MCU for sensor management. The module is designed for use in air purifiers, smoke detectors, HVAC systems, weather stations, and smart home devices. The RRH62000 is an integrated sensor module that measures key air quality parameters, including particulate matter (PM1, PM2.5, PM10), total volatile organic compounds (TVOC), Indoor Air Quality Index (IAQ), estimated carbon dioxide (eCO2), temperature (T), and relative humidity (RH). These measurements are combined into a single package, with digital outputs available for each sensor, enabling simultaneous measurement. The module features a six-pin connector for easy plug-and-play integration. The RRH62000 is available with the RRH62000-EVK evaluation kit, which simplifies the testing of the integrated sensor module. The module measures critical air quality parameters and connects to a Windows PC via USB. […]

$119 MoreSense MS-06 air quality monitor features a Sensirion SCD40 sensor and an ESP32-S3 MCU

The MoreSense MS-06 is an ESP32-S3-based air quality monitor that takes CO², temperature, and humidity readings through a Sensirion SCD40 sensor which offers reliable performance and a lifespan of more than ten years. The MS-06 monitor’s results are identical to the Aranet4’s (considered best-in-class), putting it in a pretty good spot accuracy-wise. It is the latest entry in the MoreSense line of air quality monitors and comes with a more compact design and a touchscreen display. The built-in web server runs an interface that displays measurements, historical data visualizations, setup options, and firmware updates. Operation is completely local; sensor data can be stored on the device or a microSD card. The MoreSense MS-06 air quality sensor can be used to control a ventilation system, contributing to significant energy savings. This can be achieved through your home automation system or by using a smart plug. MoreSense MS-06 specifications: Microcontroller – ESP32-S3 […]
