Solar panels in the tropics

We are deploying automated systems in the topics and hope to use solar panels, but this closed canopy in most places I'm seeing this as a challenge.Past the obvious: 'find a...

Hi Tom,

I'm with Akiba, you have to test.  A collaborator has deployed solar-augmented kit in secondary jungle and some of them got enough light, and others didn't, so it can work.  The open circuit voltage of solar panels doesn't change a whole lot in dim light, but the current drops drastically.  So you would choose an oversize panel of the same voltage (or a bit higher).

Thanks

I've been intrigued by this topic. Thinking about ways you could use drones or some kind of launcher to deploy panels above the canopy. Sadly I live in the great white north so I have no way of testing any concepts. Maybe even some kind of solar balloon that could float above the canopy. Interesting design problem.

Hey Tom,
Since the output is dependent on a couple of factors such as the solar irradiance of the place, shading from the canopy, the type of solar panels (mono, poly or amorphous) and orientation of the panels, etc, I'd suggest you use a software to simulate the different parameters to get an almost accurate estimation of the output. You can try PVsyst- it has a free month trial (I haven't used it before but I hear it's great) or any other PV software :)

Cameras - pros and cons

So, what makes a good camera for an autonomous camera trap for insects?We use a web camera in our system, which seems to work well a lot of the time, it produces...

Hi Liz, unfortunately you will still need a Raspberry Pi as host for the OAK-1 camera to reproduce our hardware setup. It's also possible to use another Linux-based system (e.g. Raspberry Pi alternatives), but I didn't test this myself and the setup process will be different to our documentation (and probably not so straightforward). I'm planning to publish the documentation website in the next weeks, but I can already send you detailed information about putting together the hardware if you are still interested.

Hello,

 

I'm working on a light weight light trap based on Bjerge et al 2021, however I opted to use an ArduCam 64mp (9152 x 6944 resolution). Designed for the pi specifically and at $60 it checks many of your criteria. I haven't put everything together yet so I can't speak for white balance and power usage, but the autofocus appears to work well from initial tests, and it is tiny.

 

Cheers,

Hubert

Awesome! it would be great to hear how you get on, maybe you can share your results here when you have them. Is the camera only for the Pi? That could be a problem for scaling as Pis are quite hard to come by at the moment.

Easy-RIDER project Workshop IV: Pollinator monitoring recording

Alba Gomez Segura

17 November 2022 2:39pm

In case you missed our webinar on Pollinator monitoring, here is the recording.

We had presentations from three teams who will be presenting their work in designing automated monitoring tools for flower-visiting insects, different ways for creating datasets for training machine learning algorithms for insect identification and how these new technologies can be integrated in traditional monitoring schemes. The talks were followed with a discussion session.

RaspberryPi-maggedon!

We are having this problem too and it might be worthy of its own thread! The lack of RaspberryPis is a big problem and we are currently looking into alternatives. We haven't found one yet, but if we do I will let you know. @Max_Sitt might have some suggested alternatives for his system?

Hi Julien,

 

we are working with the Luxonis OAK-1 which can run lightweight detection models (e.g. YOLOv5n/s) directly on-device. However you will still need a host, for outdoor deployment Raspberry Pi (e.g. Zero 2 W) is perfect. But for testing you could also use another Linux-based system as host device or just connect it to e.g. your notebook. You can find more info in the Luxonis Docs.

 

Regarding the Raspberry Pi availability, this blog post from Jeff Geerling probably sums up the current situation pretty well. I hope in Q1 2023 the situation will get better, but at the moment nobody really knows for sure.

Most interesting images / sightings 'caught on camera'

A thread for people to upload the most interesting or unusual sightings recorded by their traps. To get the ball rolling here's a coy looking crow..

No - the trap was in their path and they just walked through it. I've now moved it to a place they can't go. The biggest threat to the moths is from pied currawongs. I schedule the trap so it shuts off at least two before sunrise to try to avoid them feasting on the larger insects.

At first I was finding wings below the screen in the morning when I put our units out. So I put a game camera on the units to see what was feeding and when. I found three bird species, likely 3 individuals, quickly found it to be a good bird feeder- Song Sparrow (most frequent), House Wren, and this Tufted Titmouse. I changed my units to turn off about 1.5 hours before dawn and that worked! Nearly all the moths left the scene before the birds came to visit.

Hi Jitendra.

If they are still images, many people are using Megadetector to analyze their images. I'm not sure how it will do in species classification, but it can tell you if there are images of interest in the shots. Others here can probably give you more detailed instructions on how to use it to batch process camera trap images.

Have you considered creating a Kaggle competition? If you already have lots of images, and some that have been labelled, then this could be a good way to get people working on a solution
