RRH47000
RRH47000 is NDIR CO2 Sensor manufactured by Renesas.
NDIR CO2 Sensor
Description
The RRH47000 sensor module uses non-dispersive infrared (NDIR) technology to accurately measure CO2 in a pact package size while ensuring petitive pricing.
An integrated relative humidity and temperature sensor enables calibration and pensation of the NDIR sensor for precise operation in different environments. The integrated sensor signal conditioning and an MCU allow algorithms to use the correlation between all built-in sensing elements to improve the accuracy of each measurement.
CO2 level is a key parameter for indoor air quality. The sensor module enables active, real-time monitoring of CO2 along with humidity and temperature, allowing automated demand-controlled ventilation and environment control for better air quality, energy efficiency, and wellbeing of occupants.
RRH47000 is configurable with selectable UART or I2C interface, with a 40.8 × 19.7 × 9.1 mm package.
