Data Acquisition System Based on ATmega8

Did anyone here learn the Visual Basic before? If you did, then this data acquisition system would be a piece of cake to you! Ok, the main goal of this project is to use a PC to connect the homemade data acquisition hardware and produce the GUI for user-friendly graphical presentation. So, in this project, the important thing is using a PC for GUI display. The circuit is being built based on the ATmega8, where the chip has the on chip 10-bit resolution A/D Converter. You must make sure that you’ve fully connected the LM335 temperature sensors to the six channels ADC input. The reasons why LM335 temperature sensors are used because it can measure the temperature using two wires remotely! In this case, you’re having the choice to connect up to eight sensors with the ATmega8 TQFP package. Normally, by sending a serial of common from PC, you’ll be able to capture the analog inputs. In other hands, the readings will be displayed, either in graphically or text data format. In addition, you’re allow to record the data as… Continue reading

The Neat and Smart dsPIC33 Breakout Box

There are different types of microcontrollers in the PIC family and one of the most familiar PIC families would be the dsPIC33. The reasons why the microchip dsPIC33 frequently being used in the digital signal controller related projects because it runs at 40 MIPS, and with up to 256 Kbytes of self-programming Flash, more than 30 Kbytes of RAM and 64 to 100-pin packages. Beside that, it’s including an 8-channel non-intrusive DMA and the option of 1.1 Msps high performance A/D converters too! Today, you will try to apply this dsPIC33 into a breakout box or BoB, which it’s usually a box that a compound electrical connector is totally separated into its component connectors. Basically, the compound connectors are used where sufficient space for connections is unavailable, such as on personal computer sound cards! This means if there are only a few connections, then a breakout cable will be used here, as it’s a common matter on a smaller notebook computers. For your information, a breakout box can also mean a piece of electronic test equipment, which has been used… Continue reading

The RMS G-Meter – The Great Helper in Heavy Industrial Field!

Have you ever wondered that how the RMS G-meter function and help you off in the daily life? Well, The RMS G-meter has the ability to measure the acceleration up to five times of Earth’s gravity (The Earth’s Gravity is in ‘G’ unit). You can either put it inside or on the object whatever you want to measure the gravity. Basically, this RMS G-Meter is a microprocessor-based device that will display and update the RMS value of the acceleration levels in real time. This RMS G-Meter is made from the combination of: A single -axis accelerometer The signal conditioning A/D converter Micro-controller LCD display Battery power supply When you turn on the device, you can select either Peak mode, Average mode, or even the Integrated RMS mode. Each type of mode has its own function, which as: The Peak Mode – the device will update the highest RMS value it has measured, soon after it was activated. The Average Mode – the device will display the averaged RMS value of signal over the entire time, since it has been active.… Continue reading

RMS G Meter – The Powerful Accelerometer

RMS G Meter is considered as one of the useful acceleration measurer that ever created. RMS G Meter had been widely used in the following industries: Shipping – RMS G Meter is used for determine and verify the packages traveled with as little damage as possible. Manufacturing – It is used for vibration sensing for quality control purpose. The proper ways to calculate the RMS: Try to pick a function Then, square the function Remember to take the ‘mean value’ of the function Lastly, do take the square root of the function RMS G Meter is a smart microprocessor-based device, which can display and updates instantly the root-mean-square (RMS) values of the acceleration. There are six main components in a RMS G Meter: An accelerometer Low pass filter A/D converter Microcontroller LCD display Battery power supply We must know how to differential the four modes which: Peak Mode Once the PMS G Meter is activated, the device will update the highest RMS value it has measured. Average Mode The device will display the average RMS value of the signal all… Continue reading
