The TMP007 is the latest infrared temperature sensor from TI that can measure the temperature of an object without touching it ! 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.
