Using MonoDAQ-U-X on Raspberry Pi

Whether you are doing measurements on a remote site or keeping your brand new Macbook safe sometimes using a full-size computer to take measurements with the U-X is just not practical or economical. So let’s take a look at using the affordable but very capable Raspberry Pi to log data from the U-X. While X3 is not supported on Linux …

Processing MonoDAQ-U-X data in python on Raspberry Pi

Python is one of the most popular programming languages and for good reason, it is incredibly versatile and a very powerful tool for data processing. Let’s take a look at how to use python running on a Raspberry Pi to receive and process data from the MonoDAQ U-X. Before starting with python make sure you have completed the first part …

Remote temperature measurement with MonoDAQ-U-X

Introduction Structural analysis of an exhibition hall requires temperature measurement to complement the strain, acceleration and inclination measurements. Temperature is measured on multiple points across the roof to help distinguish between mechanical and thermal loads. Low cost temperature sensors (AD592) were used to measure the temperature and MonoDAQ-U-X was used to acquire the analog signal and bring it into a …

Can bridge collapses be prevented by continuous structural monitoring?

Wikipedia list of bridge failures features 110 entries from year 2000 onwards, including several high-profile ones like the Genoa viaduct disaster. The recent accident again prompts the question: how could it happen in 21st century with the present bridge structural monitoring abilities of the industry? Bridge building has been evolving for thousands of years, with the oldest parts of bridges …

Polcevera viaduct: a premature end of a milestone of the Italian engineering heritage

By F. Marzullo, G. Sforza Following the collapse of the stack n°9 of the viaduct on the Polcevera, which caused a huge disaster on august 14th2018, we want to elaborate on the situation surrounding an artifact of great engineering importance that only now, albeit in a terrible way, has reached an enormous reputation. After a technical description, addressed above all to …

Single board computer power consumption and heatsink temperature

Power consumption is a very important characteristic of single-board computers (Raspberry Pi, Latte Panda) since they are oftenly powered off batteries in mobile applications. MonoDAQ-U-X data acquisition device allows precise measurement of voltage and current while the data is displayed in user-friendly DEWESoft software. Additionaly also the temperature can be monitored to analyze the relation between the CPU load, power …

Measurement basics – signal to noise ratio

Let’s look at how to measure signal to noise ratio of a signal with MonoDAQ-U-X hardware and DEWESoft software. Signal to noise ratio is a value that tells us the ratio between the meaningful information in a signal and the noise  that is obscuring this information. Technically it is expressed in the ratio of the signal power to the noise …

Automating a vacuuming chamber with MonoDAQ

MonoDAQ EtherCAT modules are used to drive valves and measure pressure in a test chamber to control the vacuuming process from DEWESoft Sequencer. The air is pumped out of the vacuuming chamber by a rotary pump. Two valves control the input and output flow of the air. The pump and the valves are controlled by the MonoDAQ 4xDO EtherCAT digital …
