TE Connectivity (TE) introduces the Digital Thermopile Sensor (TSD) contactless temperature measurement system

Friday, January 25, 2019


The new Digital Thermopile Sensor (TSD) contactless temperature measurement system 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.


Target Markets

•    Aerospace

•    Industrial

•    Medical

•    Appliance

•    Smart home 

•    Mobile devices




•    Contactless temperature measurement

•    Environmental monitoring

•    Industrial process measurement and control 

•    Motion and occupancy sensing

•    NDIR gas sensing



Key Benefits

•    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



Questions to Ask During Design-In

•    What is the operating temperature range of the application?

•    Does your end application necessitate contactless temperature measurement?

•    Would your design benefit from temperature sensors that operate at low power and saves space?
