Working on a remote river monitoring project with partners Cemar.org and a local chapter of The Nature Conservancy.

Precision Sensor Board Update

        I have continued working on this project and found a probe cover and cable housing. By not using the back of the cable housing I’ve been able to modify a RM Young 41390 Sensor Junction Box and make a usable Pressure, Temp, Humidity device to fit inside the multi-plate radiation shields. I’ve made some changes to the board connections so that it will solder to the probe housing ...Read More

IMP calling sensor

A fun project was using the Electric IMP001 to communicate with an RS485 pressure transducer. The readings are delivered to the cloud and use the nice (and evolving) services of thingspeak.net. The starting point was to test the stability of an RS485 pressure sensor – and check out the then new IMP001 – two projects in one. Stability testing a pressure transducer is putting it into a bottle of wat...Read More

What’s that sensor measuring?

Wow what a great place to share about sensors. My passion has been the interface between the real world and the digital domain. The world as we know it always has layers – so while we aim for a visualized story of some aspect of the real world – say temperature or stream depth– there are many aspects of collecting the data. Last year I bought a Honeywell Internet thermostat that allows me to see a...Read More

White House announces sensor challenge

The White House Office of Science and Technology Policy, along with the EPA, NOAA, National Institute of Standards and Technology (NIST), and USGS, yesterday announced the launch  of the Nutrient Sensor Challenge. The stated goal of the challenge is: … to accelerate the development, adoption, and use of affordable, reliable, and accurate nitrate and orthophosphate sensors […] to accele...Read More
