Hi everyone! @Hubertszcz has a biodiversity monitoring project in Panama, and we have been working on quick and dirty, ultra low cost high quality insect monitoring. We built a model last year that we tested out and has been getting decent data from! I'm crossposting from the GOSH forums where we are also developing and discussing it. There's more example images there!
We got a tiny bit of funding for a couple weeks of design work and are gonna make a new version, and i'm checkin with you all to see if there's any extra things i should consider in the next design!
Here’s some design targets for it:
- be weatherproof and self-contained and functioning while left outside in the rainforest for a month at a time
- automatically turn itself on for 4 random nights during that month
- get high quality images of the insect visitors (for instance moths that are only 5mm long) that can be processed later
- be reliably usable by non-experts
- cost less than $400 in parts
- the attractive/ photographable area should be at least the size of an A4 piece of paper (210x297mm)
- adaptable to use different types of lights (We have a weatherproofed USB attachment)
- Be carry-able by foot by a person to deploy deep into the field. Ideally a person could carry 2-3 of these at a time.
- Be robust to survive travel into difficult places to reach
our current version has been built and tested over the past couple months.
I was just about to do some testing with exactly these cameras, and @tom_august and @albags saved me the trouble with the testing they did in their very similar project
I was thinking about possibly testing out the 5MP arducam SPI cameras i could control with a microcontroller for ULTRA low energy use, but i think that that would be too low resolution for our purposes. It looks like the 16mp RPI cam would be fine, but i think we will stay with the hawkeye now that we got it working and getting better images.
One of our main concerns right now is POWER. the whole thing can run on our battery for a night or two right now, but we want LONGER and i think we can get there with possibly better power management. @tom_august what system do you use to cycle your pi into lower power modes.
Let me know any other thoughts on our design!
