For applications where you just need a lot of sensors, the 8x Voltage Input Phidget adds eight 0-5V analog inputs to your VINT Hub. (See the Comaptible Products tab for a list of Hubs) Each input can be used in one of two modes: VoltageInput or VoltageRatioInput. With VoltageInput mode, you simply measure a voltage value from 0 to 5V. This mode is useful for interfacing 5V sensors and for monitoring small voltages. In VoltageRatioInput mode, you can read ratiometric sensors like potentiometers and voltage dividers, whose output voltage depend on their input voltage. The return voltage is expressed as a ratio of the return voltage to the supply voltage from 0.0 to 1.0.
Features
You can change the sample rate of each input separately,
to speeds of up to 50 samples per second. You don't need to worry
about messy power cables either; Power from the attached VINT Hub
is distributed to each input's sensor. Conversion from sensor voltage
into the units being measured is handled by our libraries when using
sensors from Phidgets. Just set the SensorType property and use the
SensorChange event and the conversion formula will be automatically
applied to all incoming data. See the API tab for more details.
Other Options
If you're looking to precisely measure a smaller voltage or need power isolation between your VINT Hub and your voltage sensor, take a look at our isolated voltage sensor boards on the "Other Voltage Inputs" tab.
