Create an Ambient-Adaptive real-time CO2 Bar

By Sheikh Shuhad

This tutorial walks you through a tiny, privacy-first web app that reads only the advertised CO2 level from a nearby HibouAir sensor using a BleuIO USB BLE dongle. Renders it as a color bar with a simple “High CO2” warning when your threshold is crossed.

CO2 Monitoring with Renesas EK-RA4M2, RRH47000 CO2 Sensor & BleuIO

By Sheikh Shuhad

This project integrates the Renesas EK-RA4M2 board with the Renesas CO2 Sensor (RRH47000) and the new BleuIO Pro Dongle (SSD025), built on the Renesas DA14695 SoC. The dongle advertises CO2, humidity, and temperature data from the sensor, displayed via the RTT Viewer.
