The TSEV01S01C90 is a contact-less temperature
measuring system for OEM use based on the detection
of infrared radiation.
The TSEV01S01C90 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 TSEC01S01C 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.
