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 – […]
