Note: The 1103_1B is identical to the 1103_1, except that you have the option of which size of Phidget cable to include.
This sensor can detect the presence of objects at a distance of up to 10cm away, depending on how well the surface of the object reflects infrared light. When an object enters the range of detection, the output voltage becomes zero, and when it leaves, it returns to 5V. The 1103 works just as well in both dark and well lit environments.
The sensor cannot detect the presence of the object if it is emitting large amounts of light, such as a light bulb.
This sensor can be read by any Phidget with an Analog Input or VINT Hub port. It will connect to either one using the included Phidget cable. VINT Hub ports can behave just like Analog Inputs, but have the added flexibility of being able to be used as digital inputs, digital outputs, or ports to communicate with VINT devices. For more information about VINT, see the VINT Primer.

This sensor comes with its own Phidget cable to connect it to an InterfaceKit or Hub, but if you need extras we have a full list down below. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
Welcome to the 1103 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the 1103!
In order to demonstrate the functionality of the 1103, we will connect it to the HUB0000, and then run an example using the Phidget Control Panel on a Windows machine.
The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1103.
After plugging in the 1103 into the HUB0000, and the HUB0000 into your computer, open the Phidget Control Panel. You will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on a Voltage Ratio Input object in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
The 1103 can detect the presence of an object at 10cm. It does not rely on the reflective properties of the surface of the object. It cannot detect the presence of the object if it is emitting large amounts of light, such as a light bulb.
The 1103 will not detect objects that are more than 10cm away, but will detect objects that are closer than 10cm. When an object is in the line of sight, at a distance of 10cm or closer, the 1103 voltage ratio will decrease from 1.0 to 0. Once the object leaves the line of sight, the value is restored to 1.0.
The 1103 works just as well in both dim and well lit areas. You may have trouble using this sensor through a pane of glass, since the IR light can easily reflect off of the surface of the glass.
The Phidget Cable is a 3-pin, 0.100 inch pitch locking connector. Pictured here is a plug with the connections labelled. The connectors are commonly available - refer to the Analog Input Primer for manufacturer part numbers.

This device doesn't have an API of its own. It is controlled by opening a VoltageRatioInput channel on the Phidget that it's connected to. For a list of compatible Phidgets with VoltageRatio Inputs, see the Connection & Compatibility tab.
You can find details for the VoltageRatioInput API on the API tab for the Phidget that this sensor connects to.
