While we admit that free honey sounds pretty good, beekeeping is not some set-it-and-forget-it hobby where you can just put bees in a box and come back in a month to collect the goods. With the world’s bee population in decline, it’s more important than ever to monitor the health of hives.
One way to do that is to count the bees as they leave and reenter the hive. You can use the data to determine how many workers are working, or to compare activity between multiple hives. If you notice the bees are gone for longer and longer periods, it’s probably because their nearby nectar sources are dwindling and they have to travel farther to find flowers.
This open-source bee counter built by [hydronics2] is designed to fit the opening of a standard hive. The bees can only buzz themselves back in by flying through one of 24 little IR break-beam gates. Our favorite thing about this build is the way [hydronics2] created the individual gates by sandwiching two boards together with headers as spacers. It’s such a simple and perfect solution.
It’s also pretty cool that the board is designed to be compatible with any Feather or ItsyBitsy board, so there are a lot of options for data handling. Check out the brief demo we planted after the break, and stick around for the build video. If you’d prefer a more hands-off approach, try computer vision.

We all know how important bees are to our ecosystems and [Kris Winer]’s bee monitor provides a great way to monitor these amazing but delicate creature’s habitats, hopefully alerting us before a disaster strikes a vital hive.
The board is based around LoRa sensor tile called Cicada but redesigned to make it smaller and cheaper. LoRa is a popular low-power wide-area network running on sub-Ghz bands designed exactly for applications like this. This board has a nice suite of sensors. It can detect UVA, UVB, and the visible spectrum of light. It can also observe the temperature, pressure, and humidity. Importantly for bees, the accelerometer can detect the various vibrations of the hive as well as disaster events like vandalism.
The data is all logged into a Cayenne dashboard which the prospective farmer could view and analyze from anywhere. [Kris] mentions that the board is relatively easy to re-spin with a different sensor suite depending on the application. Technology like this can go along way towards a more sustainable future.
Bees. The punchline to the title is bees carrying sensors like little baby bee backpacks. We would run out of fingers counting the robots which emulate naturally evolved creatures, but we believe there is a lot of merit to pirating natural designs, but researchers at the University of Washington cut out the middle-man and put their sensors right on living creatures. They measured how much a bee could lift, approximately 105 milligrams, then built a sensor array lighter than that. Naturally, batteries are holding back the design, and the rechargeable lithium-ion is more than half of the weight.
When you swap out brushless motors for organics, you gain and lose some things. You lose the real-time control, but you increase the runtime. You lose the noise, but you also lose the speed. You increase the range, but you probably wind up visiting the same field over and over. If your goal is to monitor the conditions of flowering crops, you may be ready to buy and install, but for the rest of us, dogs are great for carrying electronics. Oh yes. Cats are not so keen. Oh no.
Even if keeping bees sounds about as wise to you as keeping velociraptors (we all know how that movie went), we have to acknowledge that they are a worthwhile thing to have around. We don’t personally want them around us of course, but we respect those who are willing to keep a hive on their property for the good of the environment. But as it turns out, there are more challenges to keeping bees than not getting stung: you’ve got to keep track of the things too.
Keeping an accurate record of how many bees are coming and going, and when, is a rather tricky problem. Apparently bees don’t like electromagnetic fields, and will flee if they detect them. So putting electronic measuring devices inside of the hive can be an issue. [Mat Kelcey] decided to try counting his bees with computer vision, and so far the results are very promising.
After some training, a Raspberry Pi with a camera can count how many bees are in a given image to within a few percent of the actual number. Getting an accurate count of his bees allows [Mat] to generate fascinating visualizations about his hive’s activity and health. With real-world threats such as colony collapse disorder, this type of hard data can be crucial.
This is a perfect example of a hack which might not pertain to many of us as-is, but still contains a wealth of information which could be applicable to other projects. [Mat] goes into a fantastic amount of detail about the different approaches he tried, what worked, what didn’t, and where he goes from here. So far the only problem he’s having is with the Raspberry Pi: it’s only able to run at one frame per second due to the computational requirements of identifying the bees. But he’s got some ideas to improve the situation.
As it so happens, we’ve covered a few other methods of counting bees in the past, though this is the first one to be entirely vision based. Interestingly, this method is similar to the project to track squirrels in the garden. Albeit without the automatic gun turret part.
Bees are a crucial part of the ecosystem – without bees to act as pollinators, many plant species wouldn’t be able to reproduce at all! It’s unfortunate then that bees are struggling to survive in many parts of the world. However, [Louise Cosgrove] is doing her part – building homes for bees in old television sets.
The project started when Louise’s son-in-law left 100 (!) analog TVs at her home, having already recycled the picture tubes. That sounds kind of impolite to us, but we’ll give them the benefit of the doubt and assume they had some sort of agreement. [Louise] realised the empty television cases had plenty of ventilation and would make ideal homes for bees. By filling the empty boxes with natural materials like wood, bamboo and bark, it creates nesting places that the bees can use to lay their eggs.
We’ve seen bees on Hackaday beefore (tee-hee) – like this beehive wired for remote monitoring.

The world has a bee problem. Honey bees are a major pollinator for all sorts of tasty crops, but an estimated one-third of all colonies in the US have vanished since 2006. These mass disappearances are collectively known as Colony Collapse Disorder, and everything from pesticides to global warming to a new bee virus has been blamed for bees going MIA. Regardless of the cause, keeping the bees that do remain alive and pollinating is important work, and an intelligent bee hive could go a long way toward that goal.
Normally, bee hives are a black – err, white – box, where the bees go about their business without revealing much about it. While bees are amazing animals with an incredibly rich social structure that allows them to, for instance, team together to ventilate a too-warm hive with their wings, or gang up on invading predators, they have their limits, and knowing what’s going on in the hive helps the beekeeper to maintain an optimal environment. [Miguel’s] system, which appears to still be in the prototyping phase, aims to provide the beekeeper with data on temperature and humidity within each hive. GPS tagging allows the beekeeper to track where a hive is, which is important since hives are moved around as various crops begin to flower. The system can even keep track of the comings and goings of bees using photoelectric sensors; while [Miguel] doesn’t go into detail, we imagine that aspect working something like this bee counter we featured a few years back. And being from Portugal, [Miguel] has incorporated cork into the design of the hive, a sustainable material available locally and offering great thermal properties.
Sounds like [Miguel] is onto something here. The bees need all the help they can get, and anything that improves their husbandry will go a long way toward keeping the world fed. We’ll be watching to see where [Miguel] takes this system.
[Ken] keeps his bees remotely and can’t check on them as often as he might like to. He wanted some way of knowing when they were out of space, because that slows down their nectar collection. He knew he could do this by remotely tracking the weight and internal temperature of the hives.
His first prototype revolved around a postal scale that couldn’t be turned off between readings. This meant that he needed a bigger solar panel and battery than originally intended. For about a week, the hives were sending data to Thingspeak through an Arduino Fio over XBee.
The current iteration measures the load cells with an HX711 24-bit ADC. This sends the scale data to an Apitronics Bee unit, which adds in temperature data from the hives and sends everything to an Apitronics Hive. [Ken] will also stream it to a cloud service so he can monitor them in real-time. [Ken] wants to see as much data as possible and contribute to NASA’s HoneyBeeNet program, so he has a second Bee unit set up to handle a nearby Apitronics weather station.
