Introduction

What is Data Acquisition? Data Acquisition (DAQ) is the process of collection data from different sensors into a computer.

A DAQ System consists of 4 parts: Physical input/output signals, sensors DAQ device/hardware Driver software Your software application (Application software).

DAQ Devices

Here are some examples of DAQ devices:

To use these DAQ devices from National Instruments, you need to install the NI-DAQmx driver.

Here you find more information about NI-DAQmx.

Both these devices (TC-01 and USB-6008) are programmed in the same manner in C#. See Examples below.

 

Note! The NI-DAQmx driver do not support .NET Core, only the standard .NET Framework.

Note! Make sure to at least select "NI-DAQmx Support for .NET Framework 4.x" and "NI-DAQmx Support for Visual Studio 2019" during the installation of DAQmx.

 

TC-01

TC-01 Thermocouple is a DAQ device from National Instruments used to read and log temperature data. Read more...

Data Acquisition (DAQ) is the process of collection data from different sensors into a computer. A DAQ System consists of 4 parts: Physical input/output signals, sensors DAQ device/hardware Driver software Your software application (Application software).

In order to use the TC-01 Thermocouple, make sure you have installed the DAQmx driver first.

Firmware: If you get error using TC-01, you may need to upgrade the Firmware

USB-6008

USB-6008, or similiar, are DAQ devices from National Instruments.

You can use them preferably together with LabVIEW, but you can also use them together with Visual Studio/C#, MATLAB, Python, etc. USB-6008, USB-6001 (USB-600x), myDAQ, etc. all use the same driver, which is the NI-DAQmx.

Sensors and Actuators

Below you find information and resources about the different sensors and components you are going to use.

The sensors and components are:

 

TMP36

A Temperature sensor like TM36 uses a solid-state technique to determine the temperature. They use the fact as temperature increases, the voltage across a diode increases at a known rate.

Thermistor

A thermistor is an electronic component that changes resistance to temperature - so-called Resistance Temperature Detectors (RTD). It is often used as a temperature sensor.

Light Sensor

Light sensor, Photocell (Photo resistor), LDR (light-dependent resistor). A light sensor / photocell is a sensor used to detect light. The resistance decreases with increasing light intensity (stronger light).
