This module can be used to be connected directly to some sensors, like geophones, accellerometers, gyroscope, photoresistors, temperature sensors, luminosity sensor, sound sensors or measure of the resistance with very small variation like linear resistive encoder etc etc.
There are a document that well explain the functionality of this device.
The Theremino ADC24 offer the concretepossibility to approach thousands of possible applications that previously could not be economically and easily generated.
With little expense you enter the world of high precision measurements using the Windows 10 Operating System with all its possibilities!
This module use the new Analog Digital Converter AD7124-8 chip made by ANALOG DEVICE.
In short summary this device have 8 or 15 analog input at 24 bits (depend by the configuration). According with simple aritmetics, 24 bit means a power of 2 for 24 times generating this bignumber: 268,435,456.
That means you can read an analog electrical value with a granularity of 1/268.435.456.
By simply connecting a few wires, you create applications that would otherwise require unstable pre-amplifiers, difficult to construct, adjust and tune. Good examples are the simplest way to read load cells and the direct amplification of Geophones , accelerometers, giroscope etc. etc..
You can measure voltages and currents, with accuracy greater than that of a good tester and a thousand times more resolution. You can connect the photodiodes for weak lighting, how to slit spectrum analyzers, but even magnetometers, microbarometers, linear potentiometers for detecting shifts and fractures, load cells, analytical balances, blood pressure monitors, mechanical deflection sensors, thermocouples, pH meters, datalogger of voltages and currents, etc. etc.
with this device, connected to a Theremino Master and using the software Theremino Data Scope, you can build a very good data logger, that have a characterisics comparable with the commercial data logger that have a cost thousand of USD.
The maximum voltage applied to the inputs goes from zero volts to 3.3 Volts positive. The inputs can be directly connected to the sensors (such as Geophones or load cells), but to build a data-logger, capable of measuring higher voltages (and bear them without breaking), you will need to add two resistors per entry.
For the operation of the Adc24 are necessary:
