RRH47000 NDIR CO2 and RHT Sensor Module

Renesas RRH47000 NDIR CO₂ and RHT sensor modules operate within a range of 400 ppm to 5,000 ppm, making them ideal for various applications where air quality monitoring is critical. With a remarkable accuracy of ±30 ppm and long-term stability, these sensors can maintain their precision for over a decade.

The automatic baseline calibration (ABC) ensures consistent performance without constantly having to manually recalibrate. Additionally, the integrated temperature and relative humidity sensors provide essential data to improve environmental monitoring. The sensor is designed to operate efficiently in harsh conditions with a wide operational range of -10°C to +50°C and humidity tolerance from 0% to 95% RH.

A key focus of this sensor is the power efficiency. This sensor using less than 50 mA to function, while supporting I²C and UART interfaces, allows for easy integration into various systems. It also complies with strict CO₂ standards, such as California Title 24, RESET Grade B, WELL, and ASHRAE 62.2, ensuring it meets high regulatory demands for air quality.

Designed for durability, it’s robust against vibrations and is built to last over 10 years, making it a reliable investment for long-term projects. Despite its powerful capabilities, the compact size of 40.8 mm x 19.7 mm x 9.1 mm allows it to fit into any environment where monitoring CO₂ levels is essential.
