Technical Information
This sensor can detect the presence of a highly reflective object at 10cm, for less reflective
objects (like hands) the distance is about 5cm.
The sensor will not detect objects that are more than 5 to 10cm away depending on the type
of objects, but will detect objects that are closer than 5 to 10cm.
Coding for your Sensor
Phidget analog sensors do not have their own API, but instead their output is a voltage that
is typically converted to a digital value and accessed through the SensorValue properties and
events on a Phidget InterfaceKit. It is not possible to programmatically identify which sensor is
attached to the Analog Input. Your application will need to apply the formula from this manual
to the SensorValue to translate it into usable data.
Please see the Phidget InterfaceKit product manual for code samples, an overview of its API,
and a description of our architecture.
Other Interfacing Alternatives
If you want maximum accuracy, you can use the RawSensorValue property. To modify the
formula, substitute (SensorValue) with (RawSensorValue / 4.095)
If the sensor is being interfaced to your own Analog to Digital Converter (not a Phidget device),
our formulas can be modified by replacing (SensorValue) with (Vin * 200). It is important
to consider the voltage reference and input voltage range of your ADC for full accuracy and
range.

Analog Input Cable Connectors
Each Analog Input uses a 3-pin, 0.100 inch pitch locking
connector. Pictured here is a plug with the connections
labeled. The connectors are commonly available - refer to
