Soil Sensor Student replied to the topic Alphasense CO2, Power Issues in the forum Environmental Sensors 8 months, 3 weeks ago
Hello Shannon,
We are using version 1.0. The whole system is powered using a Voltaic brand 12volt battery. The voltage is stepped down via a DC-DC converter to power the Mayfly. The pump is powered by the battery and is switched on/off with a relay bank which is controlled by the Mayfly. The CO2 sensor is also powered by the battery, as it…[Read more]

What version of the Mayfly board are you using? And how are you powering the Mayfly? Is the Mayfly providing the power for the sensor and vacuum pump too, or is that from a different source?

Hello,
I am part of a team of Student Engineers from Minnesota State University creating a Sensor to measure CO2 concentrations in sub-surface soils. Check out the GitHub – https://github.com/bellahenkel/Soil-Sensing-Device this was created by Last semesters wonderful team.
We are using the Alphasense IRC-a1 CO2 sensor with NDIR CO2 transmitter…[Read more]

Are you sure your serial port monitor is set to the same baud rate as the serial baud rate in your program? Usually when there are nothing but junk characters, it’s a baud rate mis-match. I would suggest using a serial baud rate of 57600. Make sure you have that set in your program and on your serial port monitor. The baud rate between the s…[Read more]

Braedon started the topic Programming and troubleshooting Apogee SP-710 sensor in the forum Environmental Sensors 9 months, 1 weeks ago
I have installed some stations that use the Apogee thermopile pyranometers and pyrgeometers to measure incoming and outgoing shortwave and longwave radiation. These sensors don’t have their own source code in the modular sensors library, so I took the liberty of creating my own based on the Apogee SQ-212 files that already exist. The data I’m…[Read more]

@jamesp I wonder how the systems are faring?
neilh20 replied to the topic Using SAMD51/Wio Terminal in the forum Infrastructure and Equipment 9 months, 1 weeks ago
A follow up – I had this running for about 6 weeks last year.
The code is in my fork is at https://github.com/neilh10/ModularSensors/tree/release1/examples/samd_log_display_mmw and is available to the main at any time.
For test purposes, I positioned the temperature sensors in my office, attached to different areas round the heating vent, w…[Read more]
