Jul 02, 2021· The heart of the TVOC and eCO2 sensors is a thin layer of metal oxide. Therefore, the sensors are also called MOX sensors or MOS for short. The metal oxide is mostly tin dioxide. The metal oxide layer does not have an ideal crystal structure. Some oxygen atoms are missing and this causes a certain conductivity.

+

A NDIR type gas sensor calculates the gas concentration by using the property that gas molecules (, CO2) absorb infrared rays. Therefore, a NDIR type gas sensor is equipped with an infrared light emitter that emits infrared light and an infrared sensor that detects infrared light, and the performance of NDIR type gas sensor varies depending on the type of the light …

EEPROM, or E lectrically E rasable P rogrammable R ead O nly M emory, is a type of device that allows you to store small chunks of data and retrieve it later even if the device has been power cycled. A lot of modern microcontrollers – such as the ATmega328 – contain some builtin EEPROM, but that doesn''t mean that you can''t add more!
