TE TSD305 Digital Thermopile Sensors

The TE TSD305 Series are digital thermopile sensors in a TO5 package. The TSD sensors include an infrared sensor (thermopile) and a sensorsignal conditioner.

The TE TSD305 sensors can be interfaced to any microcontroller by an I2C interface. This microcontroller has to calculate the temperature results based on the ADC values and the calibration parameters
