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 ...

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

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 ...
