What Do I Do if My Logger Says “Self-Test Failed?”
We occasionally receive data loggers in for repair that fail their internal self-test. This usually indicates damage to either the internal power supply circuits or to the amplifier/A/D converter. Recently, we received multiple units back from one customer that shared a similar problem with the main power supply. Going back to the customer, we found … Continued
Everything You Wanted to Know About Modbus But Were Afraid to Ask
For the majority of the applications we are involved with, our data loggers, such as the dataTaker DT80, are wired directly to sensors or equipment that provide an analog signal such as a 0-10V or 4-20 mA that the logger measures and scales to the correct units such as pressure, force, temperature, etc. However, we … Continued
The Secret to Setting Up and Managing IoT SIM Cards
Have you started thinking about using the cellular network as a connection path for your IoT device or datalogger? If you are based in North America and you are not deploying hundreds of devices, you will want to read on. The Problem The North American carriers continue to lag behind the Europeans and the rest … Continued
Getting Started with Distributed Data Logging
In the first part of this series, I talked about how I see distributed data logging as an evolving trend in the field of general purpose data logging. I discussed what it is, the parts that make up distributed data logging systems, and some of the technology for connecting and communicating between the different pieces … Continued
Distributed Data Logging Overview
Unless you’re living in a cave I’m sure you have heard about the Internet of Things(IoT) or maybe the Industrial Internet of Things (IIoT). We’ve seen a lot more interest in a closely related type of project I like to call distributed data logging. You might be asking yourself what is distributed data logging and … Continued
