aquametric - new sensor deployed

October 3, 2020

We have been working on designing and releasing our next sensor version. This one focuses on using more readily available parts and being more versatile depending on the situation in which it is deployed. To read more about this sensor’s design and some rough steps to create your own, visit our new guide at guide.aquametric.live. Keep […]

aquametric - methods of measuring velocity

September 11, 2020

While stage height can provide useful data to help predict flood events or other localized events, it is sometimes not enough to be able to quantitatively measure how one water body will interact with another. The flow rate can provide this data, but in order to measure it, you need to know a) the cross […]

aquametric - more robust hardware alternative

September 2, 2020

I’ve been working on an alternative sensor version for areas where natural conditions or people are likely to damage the device. The idea of a fully enclosed PVC sensor design came from my mentor session with Bruce Dominguez. While this design will be harder to install, it will be much more resilient to damage. Currently […]

aquametric - sensor vandalized

June 19, 2020

We expected that at some point, someone would want to know about our sensor or want it removed (even though we received permission to mount the sensor), and that is why we provided contact information directly on the device. We did not expect, however, that someone would want to destroy our sensor just for the […]

aquametric - stream cross sectional analysis

May 22, 2020

Knowing the depth of the water flowing through a stream is great for knowing when it may flood or how the banks may erode over time, but in order to predict how other  bodies will interact with a stream, its often useful know the actual volume of water flowing through it. In order to calculate […]

aquametric - sensor submerged

April 28, 2020

Our sensor mysteriously stopped reporting measurements back to us yesterday around 3 am. The battery and cellular strength all seemed to be acceptable, so we were unsure what had happened to it. The last few readings from the sensor show the stream water level rising rapidly, but nothing that we hadn’t seen before in previous […]

aquametric - ota updates

April 24, 2020

The frequent trips to the stream for software updates were starting to get tiring, so we sought to implement OTA updates. We also wanted to be able to change the frequency at which our sensor wakes up and takes a measurement (e.g. hourly, every 15 minutes). The Particle Electron microcontroller we are using supports OTA […]

aquametric - quirky sensor data

April 23, 2020

Recently, we visited the sensor and did some in-field fixes to the thermistor. The temperature now seems to be sending back sensible readings now and we can see the day night cycle in the stream temperature pretty well. Our conductivity sensor, on the other hand, is behaving pretty strangely. It also shows a daily cycle […]
