Contact-less Infrared Thermopile Sensor

  • Availability: Discontinued
  • Product Code: SN-TMP007
  • Warranty Period: 12 months
This is contactless temperature sensor, based on the IR amount, and it is from TI. It can measure the temperature of an object without touching it!
The TMP007 is the latest thermopile sensor from TI, and is an update of the TMP006. The internal math engine does all the temperature calculations so its easier to integrate - you can read the die and target temperatures directly over I2C. The TMP007 also has better transient management, so you don't get as much over/undershoot when the temperature changes a lot.
Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. The embedded thermopile sensor generates a very very small voltage depending on how much IR there is, and using some math, that micro voltage can be used to calculate the temperature. It also takes the measurement over an area so it can be handy for determining the average temperature of something.
This sensor comes as a ultra-small 0.5mm pitch BGA, too hard to solder by hand. So we stuck it on an easy-to-work-with breakout board. The sensor works with 2.5V to 5V logic so it requires no logic level shifting. There are two address pins and using a funky method of connecting the pins you can have up to 8 TMP007's connected to one I2C bus. We also include a small piece of 0.1" breakaway header so you can easily solder to and use this sensor on a breadboard. Two mounting holes make it easy to attach to an enclosure.
There is a great tutorial + easy-to-use Arduino library with an example that will have you up and running in 5 minutes. The code can also be ported to any microcontroller with I2C support.

Q & A (5)
Can this direct connect to Raspberry pi 3B+ I2C pins without additional I2C shield? Thanksy ( Charles, 28/02/2019 )
I bought this TMP007, if the copper connection at TMP007 has been removed, can I still use TMP007? ( Hana, 01/12/2018 )
Hi, the copper connection is to allow the circuit connected. You may email to Thanks
can read body temperature? ( Ezza, 25/10/2018 )
Hi, yes you can measure body temperature using this item :)
can TMP007 connect with NodeMCU ? ( Hana, 16/10/2018 )
Hi, yes this sensor is compatible with NodeMCU. You can connect to I2C pins. Thanks.
What is the effective distance (in cm) to get an accurate temperature reading? ( Shamsul, 26/01/2018 )
Hi, it is not stated the effective distance to get the optimum reading. However you could refer the TMP007 Datasheet page 37 - 8.3 System Examples. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
