The TSEV01S01C10 is a contact-less temperature
measuring system for OEM use based on the
detection of infrared radiation.
The TSEV01S01C10 is equipped with an infrared
sensor (Thermopile) in front. The Thermopile Sensor
has to be pointed at the target object.
The basic working principle is:
Detection of infrared radiation
with a Thermopile sensor,
which turns incoming radiation
to an analogue voltage
Determination of sensor
temperature using a thermistor
Calculation of ambient and
object temperature using a
processing unit
Providing the ambient and
objects temperature at digital
output bus (SPI)
The basic thermopile sensor module is suitable for a
wide range of application where non-contact
temperature measurement and high accuracy are
required

ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are limiting values of permitted operation and should never be exceeded under
the worst possible conditions either initially or consequently. If exceeded by even the smallest amount,
instantaneous catastrophic failure can occur. And even if the device continues to operate satisfactorily, its
life may be considerably shortened.
