The DST1200 accurately measures distances between 40mm and ~10m. Use this Phidget 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 Overview page. 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:

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":
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.
Note: Graphing and logging is currently only supported in the Windows version of the Phidget Control Panel.
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.
You can perform filtering on the raw data in order to reduce noise in your graph. For more information, see the Control Panel Graphing page.
You can perform a transform on the incoming data to get different graph types that may provide insights into your sensor data. For more information on how to use these graph types, see the Control Panel Graphing page.
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.
The Data Rate is the reciprocal of Data Interval (measured in Hz), and setting it will set the reciprocal value for Data Interval and vice-versa.
You can modify one or both of these values to achieve different data outputs. You can learn more about these properties here.
Firmware Upgrade
MacOS users can upgrade device firmware by double-clicking the device row in the Phidget Control Panel.
Linux users can upgrade via the phidget22admin tool (see included readme for instructions).
Windows users can upgrade the firmware for this device using the Phidget Control Panel as shown below.
Firmware Downgrade
Firmware upgrades include important bug fixes and performance improvements, but there are some situations where you may want to revert to an old version of the firmware (for instance, when an application you're using is compiled using an older version of phidget22 that doesn't recognize the new firmware).
MacOS and Linux users can downgrade using the phidget22admin tool in the terminal (see included readme for instructions).
Windows users can downgrade directly from the Phidget Control Panel if they have driver version 1.9.20220112 or newer:
Firmware Version Numbering Schema
Phidgets device firmware is represented by a 3-digit number. For firmware patch notes, see the device history section on the Specifications tab on your device's product page.
If your device has a icon printed on the enclosure, it means that it has an improved filter on its VINT connection that upgrades performance when plugged into a port on a VINT Hub that also has the icon:
For details on how the maximum cable length is impacted, see the specifications tab on the product page for this device.
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.
