The Great Search: Non-Contact “Infrared” Temperature Sensors #TheGreatSearch @DigiKey @Adafruit
This week, we got a request for a STEMMA QT version of a temperature sensor that does single-point non-contact temperature.
Most of our sensors are contact: MCP9808, DS18B20, BME280, etc. They will measure the ‘ambient’ temperature next to the silicon die. But you don’t necessarily want to be in contact for measuring some items. Maybe they’re really hot! Or maybe the thing you’re measuring is far away.
We stock some IR sensors like the MLX90614, which you can breadboard with. But this sensor is a bit older, and we like to avoid hand soldering. The other sensor we liked, the TMP007, was discontinued. Now that the human temperature reading trend is waning, let’s see if better sensors are available on the market.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
