All we do is often involved with our tenet " Purchaser to start with, Rely on initially, devoting over the food stuff packaging and environmental defense for 4 In 1 Multifunction Gas Detector, Thermal Imaging Photography, Carbon Dioxide Gas Sensor, Since establishment within the early 1990s, now we have arrange our sale network in USA, Germany, Asia, and several Middle Eastern countries. We intention to get a top class supplier for worldwide OEM and aftermarket!

Personlized Products Co2 Monitor Module - ASIC AFE Integrated CO2 NDIR Gas Sensor Dual Channel Carbon Dioxide Analyzer-SDG11DF42G1 – Sunshine Detail:

General Description

The SDG11DF42G1 family of integrated thermopile sensor for NDIR (Infrared gas detection) is a dual channel thermopile sensor having an output signal voltage directly proportional to the incident infrared (IR) radiation power. An infrared narrow band pass filter in front of the sensor makes the device sensitive to target gas concentration. Reference channel provides compensation for all applicable conditions. The SDG11DF42G1 comprising a new type CMOS compatible thermopile sensor chip features good sensitivity, small temperature coefficient of sensitivity as well as high reproducibility and reliability. An ASIC AFE (Analog Front End) chip is integrated with the thermopile sensor, providing 1000 gain for the small voltage output of thermopile sensor. A input offset voltage is also added in the sensor input. The sensor output voltage can be directly converted by ADC, which elimates the precision Zero-Drift amplifier and DC-DC circuit. A high-precision thermistor reference chip is also integrated for ambient temperature compensation.
