DESCRIPTION
APPLICATIONS
The TSSP4P38 is a compact infrared detector module
for proximity sensing applications. It receives 38 kHz
modulated signals and has a peak sensitivity of 940 nm.
• Object approach detection for activation of displays and
user consoles, signaling of alarms, etc.
The length of the detector’s output pulse varies in proportion
to the amount of light reflected from the object being
detected.
• Differentiation of car arrival, static, car departure in
parking lots
• Simple gesture controls
• Reflective sensors for toilet flush
• Navigational sensor for robotics

The typical application of the TSSP4P38 is a reflective sensor with analog information contained in its output. The sensor
evaluates the time required by the AGC to suppress a quasi continuous signal. The time required to suppress a continuous
signal is longer when the signal is strong than when the signal is weak. The result is an output pulse length which corresponds
to the distance of an object from the sensor. This kind of analog information can be evaluated by a microcontroller. The absolute
amount of reflected light depends on the infrared reflectivity of the object and is not evaluated. Only changes in the amount of
reflected light, and therefore changes in the pulse width can be evaluated with accuracy.
Example of a signal pattern:
trepeat = 500 ms
tpi = 120 ms, 38 kHz

Example for a sensor hardware:
There should be no common window in front of the emitter
and detector in order to avoid crosstalk by guided light
through the window.
IR detector
IR emitter
The logarithmic characteristic of the AGC in the TSSP4P38
results in an almost linear relationship between distance and
pulse width. Ambient light has also some impact to the pulse
width of this kind of sensor, making the pulse shorter.
