Hi, I'm a student at Swarthmore College where we use a CR1000X in our Solar Lab. I have been looking into the posts on Appropedia about the CR1000 set up and the limitations of publishing to the web. We are also struggling to find an affordable and low-tech solution. I am curious to follow up and ask if more details on the solution for publishing to the web was found for this system, we would love to adopt it. Thanks, Chris ——The preceding unsigned comment was added by Cstone3, 11 March 2022
- @Cstone3 Hi Chris! What kind of logging are looking to do? I don't know if this helps you but I have built some low-cost data loggers using the lowest-cost Arduino boards available (these cost a few dollars). The photo here is an example of a logger with an SD card shield used to log air humidity (it was my testing application). —Emilio (talk) 23:38, 11 March 2022 (UTC)
- @Emilio Thanks for your quick response! We already have a data logger we use at my college, the CR1000X, which is very similar to the CR1000 that is mentioned in the original post. We use it to connect to two pyranometers (tilted and horizontal irradiation) and a pyroheliometer (direct irradiation) and it has been a part of the school's lab for several years, the only thing is that we would like to be able to publish this information of solar availability. For example, a graph that displays live information from our data logger and would allow anyone to download .csv's of the data. The lab is used for experimentation to help students learn about how solar systems engineering is done, so we have three pairs of different solar panel models for testing and measuring the performance of as well. It is true that retiring our system to use an Arduino or other micro-controller set up may be effective, though that is not currently within the scope of work. The original post implies it may be possible to augment our system with an Arduino to achieve the ability to publish our data. Cstone3 (talk) 23:51, 11 March 2022 (UTC)
- @Cstone3 Sorry for not responding earlier! I see... I do not have experience with this datalogger. I'm noting that it has an Ethernet port, and you can access it through IP communications. Since what you need is a computer, maybe this resource could work? —Emilio (talk) 22:29, 19 April 2022 (UTC)
- @Emilio no worries. yeah, Lonny put me in contact with Roger and I was able to connect to the serial connection (RS-232 was not successful). By doing so, I can, for example, type 7, and the serial response will give me the instantaneous variable output. We were hoping to use python or matlab and the serial connection to manipulate the data further, but were unsuccessful in communicating with the datalogger in such a way. I've also looked through a number of papers including the one you attached, however, I believe my professor intends to put this exploration on hiatus for the time being. I'll try bringing up future research by other students using an RPi and the IP address as mentioned at the end of the paper. Cstone3 (talk) 01:21, 20 April 2022 (UTC)
