"Almost Invisible" MEMS Gas & IR Sensors

Gas sensor (TED110)

Almost Invisible 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.

Infrared Sensor (AIR111)

Infrared Detector

Features

GAM Sensor’s infrared sensing technology is playing a vital role in creating a healthier, easier and safer tomorrow. GAM Sensor has gained worldwide recognition for the design and production of high-performance thermopile detectors and sensor modules that contribute to safeguarding homes, saving energy, and providing convenience. From motion and presence detection to gas detection, and thermometry and indoor climate control applications, GAM Sensor’s infrared sensing technology and growing infrared sensing range are meeting your challenges. Our technology senses what you need for your cutting-edge applications.
The GAM Sensor thermopile sensor consists of an array of nano-thermoelements (Graphene & TMD), which forms a sensitive membrane covered with an IR-absorbing material. IR transmissible filter is suitable for motion control, fire detection and other thermal detecting applications. GAM Sensor serves various hermetical packaging for your applications. The AIR111 output signal is directly proportional to the incident radiation power largely independent from the wavelength. Our nano-material technology guarantees a highly reliable quality and gives you the best price for your applications.
GAM Sensor now offers Thermopile Detectors in compact SMP packaging. This enables standard SMT assembly processes and provides for small dimensions. These detectors are equipped with an internal thermistor as a temperature reference for thermopile temperature compensation.
