Made by Renesas, the single-channel, non-dispersive infra-red module is called RRH47000 and has automatic baseline calibration for measurement from 0 to 5,000ppm.
Also in there are temperature and humidity sensors, and a microcontroller to communicate the readings.
Relative humidity is measured to ±3.5% and operation is over -10 to + 50°C.
The component distributor is also offering the associated evaluation kit, RRH47000-EVK, including Renesas’ ESCom general-purpose sensor interface, which has a USB-C interface for computers running associated evaluation software, and a daughter board carrying the CO2 sensor.
“The software GUI simplifies sensor data visualisation and supports all operational methods for Renesas environmental and flow sensors,” said Mouser.
ESCom also has a female PMOD connector for connecting additional sensors via I2C, and a male PMOD connector for communication with some of Renesas’ microcontroller evaluation kits.
Applications are foreseen in air-conditioning, demand-controlled ventilation, and in appliances.
