There are now many competing wireless standards, each with its own advantages and disadvantages in battery power consumption, transmission distance, and applicability to different uses. Which is the best wireless standard for your application? Download this whitepaper. Competing wireless standards There are many competing wireless standards including cellular, WiFi, Bluetooth, Zigbee, LoRa and SigFox. Each [...]
Data acquisition is the sampling of continuous real world information to generate data that can be manipulated by a computer. Acquired data can be displayed, analyzed, and stored on a computer. A PC can be used to provide data acquisition of real world information such as voltage, current, temperature, pressure, or sound. The components of [...]
What Is Signal Conditioning? Signal conditioning is the part of a data acquisition system that interfaces to a sensor. Most sensors require some type of accommodation to turn their input into a linear voltage that can be measured by a data acquisition computer. Often, the signal is too "small" and must be changed to a [...]
To give you an idea of what should be included in a design proposal, here is an example device design proposal that outlines the key deliverables and documentation items that a full proposal should address in detail. Voler Systems div. of Strawberry Tree Inc. Example Device Design Proposal Date: February 12, 2009 Proposal No.: V-XXX [...]
The most common sensor is a temperature sensor, and the most common temperature sensor is a thermocouple, and yet most people do not know how a thermocouple works. They are one of the most complex sensors to measure, yet they are very low cost and rugged. If you do not understand cold junction compensation you [...]
Over the last decade the growth rate of sensor networks has been extraordinary, driven by applications that use sensors to automate the control of systems. Sensors improve energy conservation and process efficiency in commercial, industrial, and consumer settings. Download a free whitepaper "Briefing on Thermocouple Technology" and read user stories to see how Voler deliver [...]
