TE Connectivity TSD305 Digital Thermopile Sensor

TE Connectivity (TE) introduces the Digital Thermopile Sensor (TSD) contactless temperature measurement system which addresses a full range of critical design and performance demands: accuracy, speed, low power/energy efficiency, and limited space requirements. The TSD sensors include an infrared sensor (thermopile) and a sensor signal conditioner, and can be interfaced to any microcontroller by an I2C interface.

TSD sensors provide a cost-effective alternative to competitor offerings, as well as, analog sensors which require additional components to deliver similar functionality and results. TE Connectivity is a global leader in developing sensor solutions for harsh and complex environments and TSD is an example of our ability to work with clients across a wide range of industries to provide the type of smart, cost-effective solutions they require.



  • Measure temperature without physical contact and low current consumption
  • Support greater design flexibility with improved EMI resistance and the need for fewer components like low offset/low noise amplifier and associated filters
  • Fit into limited spaces with a small, TO5 package
  • Streamline integration with an I2C interface
  • Deliver high accuracy ±1°C at temperature ranges from 10°C to +85°C with a factory calibrated sensor
  • Help eliminate problems with dust, dirt, and debris with a sealed sensor housing
  • Enable accurate measurement with 10° or 88° field of view options
  • Deliver superior price to performance while delivering the same measurements



  • Contactless temperature measurement
  • Environmental monitoring
  • Industrial process measurement and control
  • Motion and occupancy sensing
  • NDIR gas sensing
