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. The evaluation kit includes a USB cable, ESCom board, RRH62000 sensor module, and a Quick Start Guide.

The RRH62000-EVK software, ES-Eval, provides a user-friendly graphical interface for configuring and evaluating the RRH62000 environmental sensor module. It features blocks for measurement control, sensor selection, algorithm configuration, signal analysis, and real-time data visualization, allowing users to easily manage and monitor the sensor’s performance. The software also automatically checks for and installs firmware updates for the ESCom communication board upon startup, ensuring optimal functionality. Users can download ES-Eval from the Software Downloads section on the Renesas website.
The documentation for the kits includes a quick start manual, a list of components (BoM), circuit diagrams, and PCB design files for development and production purposes. all can be found on their respective product pages.
Earlier, we covered the STM32-based Indoor Air Quality Sensor, which connects to Raspberry Pi or Arduino. We also wrote about the Qsen-07, the AirGradient One, and Studio LUFF’s Air Quality Sensor, which is built around the ESP32-S3 wireless module. Feel free to check those if you are interested.
At the time of writing, I can see that all the major distributors have this board available on their websites including Mouser where the RRH62000 module is available for $38.08 and RRH62000-EVK is sold for $100.
