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 ...

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 ...

ScioSense has created a gas sensor that outputs CO2, volatile organic compound and air quality indices. Inside the 3 x 3 x 0.9mm LGA package are four separate metal oxide gas sensors, each with its ...

Infineon Technologies introduces the XENSIV PAS CO2 5V sensor, using PAS technology it improves energy efficiency by adapting ventilation to actual occupancy.
