Renesas RRH47000-EVK board integrates RRH47000 CO2 sensor with ±75 ppm accuracy, relative humidity and temperature sensors

Renesas RRH47000 CO2 sensor

Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) within the 0-5000 ppm range. The sensor also includes built-in sensors for relative humidity and temperature, operates at low power, and supports either UART or I2C interface to the host. These features make this device useful for applications like HVAC systems, industrial automation, building control, air quality monitors, home appliances, IoT devices, and agriculture. Previously we have written about the Sensirion SCD40 CO2 sensor which also uses NDIR to measure CO2 levels very accurately, while the Infineon PASCO2V15 CO2 sensor relies on photoacoustic spectroscopy (PAS) to detect CO2 levels. The Sensirion sensor can also measure humidity and temperature, but the Infineon sensor is designed to measure CO2 only. Renesas RRH47000 specifications: CO2 sensor Measurement range – 0 ppm to 5000 ppm Accuracy – […]

STMicro’s low-power ST1VAFE3BX AI biosensor integrates biopotential signal monitoring and motion tracking

STMicro ST1VAFE3BX biosensor

STMicroelectronics (STMicro) has announced the ST1VAFE3BX biosensor, a highly integrated chip that combines “cardio and neurological sensing with motion tracking and embedded AI functionalities,” and is targeted at healthcare and fitness wearables. The ST1VAFE3BX biosensor chip integrates biopotential inputs with an accelerometer and a machine learning core for reduced power consumption. It features a complete vertical analog front end (vAFE) for simplified detection of vital signs in electrocardiography, electroencephalography, and other healthcare monitoring applications. Inertial sensing by the accelerometer is synchronized with biopotential sensing “to infer any link between measured signals and physical activity.” The integrated machine-learning core (MLC) and finite state machine (FSM) allow for ultra-low-power and accurate biopotential input recognition at a degree of responsiveness that is reportedly faster than the current industry standard. The ST1VAFE3BX is aimed at applications in healthcare and fitness wearables such as smartwatches, smart patches, sports bands, connected rings, and smart glasses. It […]
