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 […]
