What do expansion peripherals do, and how is integrating them helpful? Expansion peripherals have two purposes: to expand the capabilities of the data logger, both in channel count and functionality, and to improve measurement quality. What if we could provide both and make it easier... 続きを読む著者: Janet Albers | 最終更新日: 10/25/2017 | コメント: 2
Have you ever noticed a message saying that your CRBasic program compiled in PipelineMode or SequentialMode? What does it mean? And, when does it matter? In this article, we’ll look at these two modes. Sequential Mode Let’s start with the more straightforward mode: SequentialMode. The CRBasic Editor... 続きを読む著者: Timothy Jeppsen | 最終更新日: 10/11/2017 | コメント: 8
As soon as people learned that we were replacing the CR1000 datalogger with the CR1000X datalogger, they asked us these questions: “Can I load a program I wrote for my CR1000 into a CR1000X?” and “Will the CR1000X fit in the same space as my... 続きを読む著者: Dirk Baker | 最終更新日: 10/03/2017 | コメント: 8
You may be familiar with R for data processing and analysis. But do you know how to easily import data that is in Campbell Scientific’s TOA5 format into R? In this article, I’ll briefly discuss R and TOA5, and then share a function to create... 続きを読む著者: Garrett Wheeler | 最終更新日: 09/27/2017 | コメント: 0
We realize that designing a custom, high-quality automated weather station to fit your needs can be challenging, as there are many considerations to keep in mind. To help you with this task, we have recently created three new resources that I’ll introduce you to in... 続きを読む著者: Chod Stephens | 最終更新日: 09/13/2017 | コメント: 4
To help environmental researchers who measure solar radiation improve their measurements and simplify their lives, Campbell Scientific and Apogee Instruments teamed up to develop a new sensor. This new sensor combines features from higher-end blackbody thermopile pyranometers and lower-end silicon photocell pyranometers. The CS320 Digital Thermopile... 続きを読む著者: Dana Worley | 最終更新日: 08/30/2017 | コメント: 3
If you have read recent revision history for the Device Configuration Utility (also known as DevConfig), you may have run across the following note: “New USB drivers (RNDIS) were added for [supported] datalogger.” What's that all about? you may have wondered. Sounds boring, eh? We think it... 続きを読む著者: Timothy Jeppsen | 最終更新日: 08/02/2017 | コメント: 3
It should come as no surprise that the CR1000 datalogger (introduced in 2004) has been an incredibly successful data logger. With nearly 100,000 deployed, this data logger has been installed on every continent on the earth. Using the design success of the CR1000, Campbell Scientific... 続きを読む著者: Dana Worley | 最終更新日: 07/19/2017 | コメント: 0
In an April 2016 blog article (“Handling New Device Drivers in a Changing Windows World”), I wrote that Campbell Scientific was ending Windows XP support for our hardware device drivers. In that article, I also mentioned that Windows XP support might end for other products... 続きを読む著者: Alan Hinckley | 最終更新日: 06/14/2017 | コメント: 13
If you are considering using pyranometers in your measurement application, there are many things you should know about them and how they work. Having this information in hand will help ensure you select the type of pyranometer most suitable for the data you need for... 続きを読む著者: Bruce Smith | 最終更新日: 06/08/2017 | コメント: 3
Have you ever heard someone mention "ET" and wondered what it meant? Assuming the person wasn’t talking about extra-terrestrials or Entertainment Tonight, the conversation was probably about evapotranspiration. Evapotranspiration (or "ET") is the water lost through plant transpiration and soil and plant evaporation. The images... 続きを読む著者: Gary Roberts | 最終更新日: 05/31/2017 | コメント: 2
Maybe you’re like me when it comes to skipped scans. I have always disliked seeing skipped scans in my data loggers. I have been trained to watch out for them and do my best to write my CRBasic programs in a way that makes them... 続きを読む著者: Bart Nef | 最終更新日: 05/17/2017 | コメント: 8
Although air temperature and relative humidity (RH) sensors provide the benefit of an economical means to collect measurement data for two parameters, there are some issues related to these sensors that you should be aware of. In this article, I’ll provide some background on air... 続きを読む著者: Janet Albers | 最終更新日: 05/04/2017 | コメント: 0
Are you wondering what size battery and solar panel you need to run all of the devices in your data acquisition system? How will you know if your power supply can keep pace with your needs? To get these answers, you will need to estimate the... 続きを読む著者: Robin Deissinger | 最終更新日: 04/19/2017 | コメント: 0
The mention of Earth Day often stirs up thoughts in our minds of how we can reduce, reuse, and recycle. It may be easy to think of ways we can improve our habits in our homes, but it may be a little harder to come... 続きを読む著者: Carolyn Ivans | 最終更新日: 04/13/2017 | コメント: 0
If you are a Campbell Scientific customer, you may have heard of SDMs and multiplexers. But recently we added a new family of peripherals, called CDMs, to our product line. So, what are CDMs? How can they help you with your measurement needs? How do... 続きを読む著者: Dana Worley | 最終更新日: 04/05/2017 | コメント: 0
IP communication has significantly changed the way many of us access our data loggers. It is reliable, fast, and readily available—anywhere you have access to "the Internet," you have the ability to use this protocol to communicate with your data logger. Sometimes, however, network access to... 続きを読む著者: Gary Roberts | 最終更新日: 03/23/2017 | コメント: 2
Pointers are a great tool for CRBasic programs. If you use them carefully, pointers can reduce the amount of program code you need to write, thereby increasing your program’s efficiency and enabling you to use less memory. (Your program can run faster because it does... 続きを読む著者: Paul Smart | 最終更新日: 03/08/2017 | コメント: 6
Have you ever set up a Campbell Scientific data logger as a Modbus server and discovered that your data was not arriving at your SCADA system as you expected? You may have quickly realized two things: troubleshooting the communication problem is not an easy task,... 続きを読む著者: Jacob Davis | 最終更新日: 02/22/2017 | コメント: 8
Have you come across situations where you want your data logger to initiate data retrieval, rather than your PC? For example, do you have an environmental condition that you want to transmit alarm data for? Although IP-based communication is prevalent, sometimes you may need data-logger-initiated communication... 続きを読む
