The DST1200 accurately measures distances between 40mm and ~10m. Use this Phidget when you for motion sensing, object detection, or spatial awareness. This Phidget connects to your computer through a VINT Hub.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Use a Phidget cable to connect this device to the hub. 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.
The DST1000 uses reflected ultrasonic waves to measure distance. Use this Phidget for motion sensing, object detection, or spatial awareness. The sensor will measure the distance of as many as 8 objects at the same time, from 40mm to ~10m in optimal conditions with an accuracy of about 10mm.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the following channel:
2. Double click on the channel to open the example program. This channel belongs to the DistanceSensor channel class:
In your Control Panel, double click on "Sonar Phidget":
1. Setting up your Programming Environment
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
In the Phidget Control Panel, open the channel for your device and click on the 
icon next to the data type that you want to plot. This will open up a new window:
If you need more complex functionality such as logging multiple sensors to the same sheet or performing calculations on the data, you'll need to write your own program. Generally this will involve addressing the correct channel, opening it, and then creating an Event Handler and adding graphing/logging code to it.
The quickest way to get started is to download some sample code for your desired programming language and then search google for logging or plotting in that language (e.g. "how to log to csv in python") and add the code to the existing change handler.
The Change Trigger is the minimum change in the sensor data needed to trigger a new data event. The Data Interval is the time (in ms) between data events sent out from your Phidget. You can modify one or both of these values to achieve different data outputs. You can learn more about these two properties here.
The DST1200 has a Quiet Mode which reduces the volume of the sound pulses used by the sonar sensors. While the sound that this Phidget makes is audible in either mode, it is much less noticeable with quiet mode enabled. By enabling quiet mode, you will decrease the maximum sensing range and the number of reflections detected. Quiet mode also consumes less power (see product page specifications for details).
When you receive data from the DST1200, you will end up with an array of sonar reflections that each have a distance and an amplitude. The distance, of course, refers to how far away the object is. The amplitude gives you a general idea of the size of the object. The amplitude value can range from 3 to approximately 900, with 3 being a very small reflection and 900 being a very large reflection. In some applications, you will want to ignore reflections with an amplitude you deem is too small.
The DST1200 will fire saturation error events when the nearest reflection is closer than 40mm from the sensor. At this range it is too close for the sensor to accurately determine the range of the object.

Errata: The enclosure for the DST1200 may state the range as being 220mm to 10m, but it is actually 40mm to 10m, as listed in the specification table.
* - Current consumption varies depending on selected data interval. See the graph below for details.
