gam sensor : Gas Sensor

Features

The TED110 is metallic oxide semi-conductor type MEMS gas sensor for monitoring indoor air quality. It is the smallest ultra-low power multi-gas sensor with high sensitivity and containing ASIC. Its design containing pre-installed software and the specific algorithms enable to detect multi-gas and measure the temperature. This sensor is consisted of nano-particle metal oxide sensing layer, micro heater, micro thickness membrane and Read-out IC: these components, together, provide high sensitivity, low-power consumption, fast response, small size and long-term stability.
TED110 is a multi-gas sensor for monitoring Carbon monoxide(CO), combustible gases and a volatile organic compounds(VOCs). Additionally, it can be used as an equivalent carbon dioxide(eCO2) sensor.
