3 Description
The TMP007 is a fully-integrated microelectro-
mechanical system (MEMS) thermopile sensor that
measures the temperature of an object without direct
contact. The thermopile absorbs passive infrared
energy from an object at wavelengths between 4 um
to 16 um within the end-user defined field of view.
The internal math engine combines the
corresponding change in voltage across the
thermopile with the internal cold-junction reference
temperature sensor to calculate the target object
temperature. The TMP007 also provides nonvolatile
memory for storing calibration coefficients.
The TMP007 is designed with portability and power in
mind, and can easily be placed in the tightest of
spaces while using standard surface-mount assembly
processes. Low power consumption also makes it
well suited for battery-powered applications.
The TMP006 offers a reduced feature set. The
TMP006 offers similar performance as the TMP007,
but does not contain the math engine or nonvolatile
memory.
The Infrared thermopile sensor is specified to operate
from –40°C to +125°C. It is possible to measure
object temperature beyond the device operating
range as long as the device itself does not exceed
the operating temperature range (–40°C to +125°C).
