Description
This module can be used to be connected directly to some sensors, such as geophones, accelerometers, gyroscope, photoresistors, temperature sensors, light sensor, sound sensors or resistance measurement with very small variations such as linear resistive encoder etc etc.
There are a document that explains well the functionality of this device.
The Theremino ADC24 offer the concrete possibility of approaching thousands of possible applications that previously could not be generated economically and easily.
With little expense you enter the world of high-precision measurements using the Windows 10 operating system with all its possibilities!
This module uses the new Analog Digital Converter AD7124-8 chip made by ANALOG DEVICE.
In short summary this device has 8 or 15 24-bit analog inputs (depending on the configuration). According to simple arithmetic, 24 bits means a power of 2 by 24 times generating this bignumber: 268,435,456.
This means that an analog electrical value with a granularity of 1/268,435,456 can be read.
Simply by connecting a few wires, you create applications that would otherwise require unstable preamplifiers that are difficult to build, adjust, and tune. Good examples are the easiest way to read load cellsand direct amplification of geophones, accelerometers, gyroscopes etc. etc.
It is possible to measure voltages and currents, with an accuracy higher than that of a good tester and a resolution a thousand times greater. You can connect photodiodes for weak lighting, such as cutting spectrum analyzers, but also magnetometers, microbarometers, linear potentiometers to detect displacements and fractures, load cells, analytical scales, blood pressure monitors, mechanical deflection sensors, thermocouples, pH meters, voltage and current dataloggers, etc. etc.
with this device, connected to a Theremino Master and using the software Theremino Data Scope, you can build an excellent data logger, which has a feature comparable to the commercial data logger that has a cost of thousands of euros.
Security Considerations
The maximum voltage applied to the inputs ranges from zero volts to 3.3 positive volts. The inputs can be connected directly to sensors (such as Geophones or load cells), but to build a data-logger, capable of measuring higher voltages (and withstand them without breaking), it will be necessary to add two resistors per input.
For the operation of the Adc24 you need:
1) HAL application with version 6.6 (or later), which you download from this page.
2) A Master module with firmware 5.0 (or later), which you download from this page.
