QCIOT-RRH47000POCZ NDIR CO2 Sensor PMOD
Description
The QCIOT-RRH47000POCZ Evaluation Board
(RRH47000 EVB) demonstrates the functionality and
performance of the RRH47000 NDIR CO
The RRH47000 uses nondispersive infrared (NDIR)
technology to accurately measure CO
of the RRH47000 EVB is generic so that customers
can embed the sensor into their specific applications.
The board provides a standard Pmod
2
(extended I
C) connection for the onboard sensor to
plug into any required MCU evaluation kit with a
matching connector. The RRH47000 EVB can be
added to the end of a daisy-chained solution with
multiple Type 6/6A devices on the same MCU Pmod
connector.
The software support included with the Renesas IDE
2
(e
studio) allows for code generation to connect the
device and the MCU in order to significantly reduce
development time. With its standard connector and
software support, the RRH47000 EVB is ideal for the
Renesas Quick-Connect IoT to rapidly create an IoT
system.
