A two channel silicon- based thermopile in a TO-5 package that includes integrated electronics which incorporate an industry standard digital SMBus interface. Each small active area size is 1.2mm x 1.2mm.
Excellent for gas analysis, environmental monitoring, HVAC and smart home/building control
The digital platform supports easy integration and provides rapid development due to the integrated amplifier, A/D, DSP, MUX and communication protocol.
