Sensors / Feed

Want to talk about sensors that don't quite fit into any of our tech-specific groups? This is the place to post! From temperature and humidity to airflow and pressure sensors, there are many environmental sensing tools that can add valuable data to core conservation monitoring technologies. With the increasing availability of low-cost, open-source options, we've seen growing interest in integrating these kinds of low bandwidth sensors into existing tools. What kinds of sensors are you working with?

Scale with data logger

Hello all,   I am curious if anyone is aware of a scale with high precision that is capable of data logging as well. Though we have found some that may work in a lab...

1 0

Hi,

Can you clarify what you mean by "does not work"?

If I were to guess, I'd say the firmware temperature compensation tables for the load cell tops out at 40 deg C (104 deg F).  Everything else should still function to 70 deg C, which is the most common and most lax rating for electronic components.

If this is the case, then the scale probably still retains precision (output is repeatable) even if it is inaccurate (output is wrong-ish), so it's possible to calibrate it.  This could be as simple as tabulating the measured weights of standard weight samples at different temperatures, to adjust the output of your scale in post processing.  Unfortunately this means you also need to log the temperature, and you'd want to store the scale at close to ambient temperature so it quickly equilibrates (a good idea regardless) when you need to use it.

Hi Guy,

Sparkfun carry an ECG module, but I don't know if this will work with sheep/goats.  They've got lots of temperature sensors too, but I would look into something like MAX30205 if you need accuracy.

Do you mean the sensor itself (that you're going make a tag out of) or a datalogger that records heart rate (sensor incoporated into a tag already)? Vectronic make some good terrestrial animal physiological sensors.

A great proximity system you've developed @LuciKirkpatrick ! Amazing! I am curious how you deal with having tags in receive mode long enough to ensure a contact is logged? What's the chances of a contact being missed because a transmission doesn't overlap with a receiver being on? It seems like not very often given the comparison with camera trap data! 

Thanks so much for sharing and looking forward to reading more about the build.

Cheers,

Rob

 

 

Hi @Rob+Appleby , thanks for your kind words about our system! We ge around this by ensuring that the tag is in receive mode at least as long as the pause between two proximity transmissions. There is still the odd chance that some interference occurs or two or more transmissions collide, but generally it is pretty reliable.

 

Hi @LuciKirkpatrick 

Aha! A great strategy. I thought it might have been a 'wake on radio' solution, but the overlapping wait time is a really nice solution. Again, a great solution and looking forward to more build details etc., as they arrive.

All the best,

Rob

Hi All, sorry for the delayed response.

"In studies that often require deploying a half-dozen sensors or more, a sheer quantity of batteries becomes a major logistical hurdle. This is a similar problem we see with some solar systems: once deployed, they can be great (solar panel + charge controller + battery pack), but the deployment logistics can be extremely tricky from a bulk and weight perspective."

I agree, I don't believe that it should be necessary to be utilising such giant batteries & solar systems to support audio recording devices with the current developments of batteries and very low power devices, it annoys me that lead-acid batteries actually still exist.

I am assuming that the decision on batteries and photovoltaic systems would be based on availability and cost, or are they specific to acoustic devices?

Thanks All,

Adam.

Hi guys. Frontier Labs designed the Solar BAR for the Australian Acoustic Observatory (you mihgt have seen the WildLab video about it: https://www.youtube.com/watch?v=ohQURr74OvE&list=PLWcz3iwCnCqRL193GvknRWQd1_kG7Rs4g&index=1).

vIn answer to your question, we are currently putting together some short videos showing the design decisions we made during developme and why we made them. The weight vs battery power is something we take incredibly seriously, and is the reason for a lot of cool features you might not notice otherwise. Please let me know if you have any specific questions you would like covered and I'll do my best to get them answered by our engineers :) Nic

Hi Adam,

My name is Nicole, I work at Frontier Labs - we also make bioacoustic recorders (BARs) and are based in Brisbane, Australia. Yay for Australian tech!

We have been making acoustic recorders for more than 10 years (we made the recorders for the Australian Acoustic Observatory) and are always looking to innovate. These are great questions! We do get asked for the remote verification occassionally, but at the moment localization is a feature we are perfecting above and beyond what is currently available, so no work on this at the moment.

I'd love to find out more about your studies and see if we could help you answer some of these questions based on what we know about market trends.

Please feel free to get in touch with me if you'd like more info. PS I am not one of the engineers, but I have their ear haha

Hi @Rob+Appleby !

The implementation in the Vectronic camera collar is purely store on board - no transmission.

I believe they simply stuck one of the Foxeer action ("Box") cameras inside and wakes it up and triggers it according to the camera schedule uoloaded to the collar (still and video options). 

RunCam is another manufacturer of FPV and action cameras which might be interesting for you.

Cheers,

Lars

 

Hi Lars,

I have a colleague that's successfully used the Mobius cam system (https://www.mobius-actioncam.com/) for camera collars as well. RC cams are popular choice it seems. I have been attempting to tweak cheaper 'cube' cameras (e.g. https://tinyurl.com/w72kh77r) to do a similar job. I am using a bit of Frankestein's monster array of small control boards, including an Adafruit low power timer (https://www.adafruit.com/product/3573) and a SparkFun pro mini (https://www.sparkfun.com/products/11113). I am using an SMD transistor as a switch to control power, and another could be added to control settings if needed. Hoping to do a tutorial on it at some point in case there's any interest. 

Cheers,

Rob

Would certainly be cool to see a tutorial on this! Looking forward to that!

Hi and thanks for your tips, Akiba!

I was actually thinking about the little greenhouse effect today when leaving the box in the afternoon sun. It is a rather cold environment in Greenland were I will deploy these though, so I may be OK. I can always give the tops a bit of white or silver paint. For the base station, I like to be able to see the LEDs directly on the board. This will also not be left out in the sun.

I will try to get some 2mm acrylic sheet for the mounting plate, thanks!

Cheers,

Lars

I realised I actually had a piece of FR-4 fiberglass (perfboard) lying around so I used this as mounting plate. I have also tried fixing the magnet (reed) switch to the plate to hold it in place at the bottom of the box. Will do some neater cable managing as I get the remaining parts. I will try to fit a lipo solar charger next to the radiofeather. I realised that it will be hard to attach USB plugs (for reprogramming or diagnostics) but have ordered some cables with angled plugs hoping they will fit. 

I am still considering an additional reed switch as a on-off switch.

Almost done with the trap alarms.

I added an additional buzzer (with internal circuitry) to get more noise. The added benefit is that the slightly different tunes creates interference that makes the sound much more annoying ;)

I added magnetic on-off switches to all units (under the power managiing unit). The trap release reed switch is located on the other side. I raised the base plates a bit to make room for the lipo batteries underneath them. 

Still need to do some more testing on power usage and reliability. I managed a range of 2.5 km, but I believe I could get more when I find a place with better line of sight. I will try to test it over water at a fjiord.
