CO2 sensor module for smart, industrial and IoT applications

Mouser now supplies the RRH47000 CO2 sensor module from Renesas Electronics. The device is a high-accuracy, single-channel NDIR module for reliable CO2 monitoring and high-quality metrics to enhance air quality in industrial building controls, HVAC, IAQ, smart cities, factories, and appliances, demand-controlled ventilation, air purifiers, wireless access points, and IoT applications.

The device features an efficient design with automatic baseline calibration (ABC) for measurement from 0ppm to 5000ppm, with an integrated MCU for processing and output, combined with a single-channel NDIR CO2 sensor with an integrated humidity and temperature sensor, featuring ±3.5% RH sensitivity for accuracy. With a wide -10C to + 50C operation range, the device eradicates the necessity for additional compensation components, making it excellent for applications that must meet standards like California's Title 24, RESET Grade B, WELL, UBA, and ASHRAE 62.2.

Mouser also offers the Renesas Electronics RRH47000-EVK evaluation kit for the RRH47000 CO2 sensor module, enabling simultaneous carbon dioxide (CO2), temperature, and humidity measurements via the RRH47000 daughterboard. The kit includes a USB-C connector for interfacing with computers running the intuitive evaluation software (ESCom board) and a PMOD pin connector for connecting with MCU evaluation kits. The user-friendly software GUI simplifies sensor data visualisation and supports all operational methods for Renesas environmental and flow sensors, making the kit excellent for comprehensive sensor evaluations.
