Hello,

I am looking to make my own solar charging circuit for a remote datalogging system. I have a 3-AA battery holder and I am planning on using 3 AA NiMh 1.2V batteries to be placed in the battery holder. I am also planning to use a 1N5817 blocking diode, so current does not get drawn back to the solar panel.

If the batteries are wired in…[Read more]

Hi all,

Just wanted to update here with our results. We deployed our datalogging device in the NE Branch of the Anacostia River right next to USGS Site # 01649500 (http://waterdata.usgs.gov/usa/nwis/uv?site_no=01649500). We deployed here mainly so that we had an easy way to verify the accuracy of our sensors by comparing it to USGS’s data. We…[Read more]

Thanks for sharing Neil, thats pretty interesting. We are developing a similar project in my university class — server software for collecting data from environmental sensors either via wireless http or SD card, with a front-end interface with map and graph displays and integration of other data sources (weather, USGS water service). We are also…[Read more]

Thanks for the information everyone.

I drew a diagram of the physical construction of the water quality system as I have envisioned it, which I’ve attached below. I wanted to ask your thoughts about the design, particularly any apparent flaws you might see. Do you think there will be sediment buildup inside the stilling well? Is the sensor…[Read more]

Hi Dave, Rene, Neil,

Thank you very much for sharing your information, it is a great help.

Dave, that is a good point in regards to sediment build up if one were to enclose the sensors as I had initially described. PVC piping to enclose sensors/sensor housing is a good idea. My initial thoughts would be to have the waterproof-encased data…[Read more]

Hello,

I am thinking of developing a remote, continuous water quality system with an Arduino data logger and various sensors (pH, turbidity, nitrates, DO, temperature, streamflow) with a GSM module to send the data over the cellular network to a remote server. I wanted to inquire about how to implement such a system in smallish streams (e.g., a…[Read more]
