The prototype used an Arduino communicating over I2C to the sensor and an OLED screen, which he eventually put in a 3D printed case to carry around to sample CO2 concentration in various real ...

Its MH-Z14A NDIR CO2 sensor and GP2Y1010AU0F optical dust detector are read by a WiFi-enabled microcontroller, this time the Arduino Nano RP2040 Connect, which ultimately reports its findings to ...

Tiny CO2 sensor works at high concentrations Sensirion has introduced a sensor for measuring high concentrations of CO2, based on a thermal conductivity technique. Called STC31, it is aimed at ...

Gas Sensing Solutions (GSS) of Cumbernauld has added an I2C interface to its ‘CozIR-LP’ low power CO2 sensor – which consumes only 3mW, claimed to be 50x less than competitors. “An I 2 C interface ...
