Blue tooth has very limited range . I keep it really simple and use one of these. Lasted 2 years on one set of batteries.
Yes ... I used ones similar to this when I was monitoring temperature and humidity in my long hive .. the don't transmit so it's a manual check - I used to check 2 or three times a day - for about 2 years. It told me that my bees maintained a temperature significantly above the ambient temperature and that the relative humidity was generally aboive 80% - often as high as 85%. The hive was heavily insulated and I was interested in what temperature the bees maintained and whether the insulation assisted them in maintaining a constant temperature .. I also had a view that being able to maintain a high temp and humidity had an effect on the varroa levels.
Thanks. Looking at a device that can store the data. Every time I get within range, it’ll will connect and transmit the data over to the app on my iPhone.
You have probably found what you seek then. Only observation I would make > just as with the remote sensor type I use, it's likely to be embedded in wax/propolis if it's left hanging between frames for any length of time and give you dodgy data.
I was wondering how you could combat this with the wax and propolis.. I presume one of the first things a colony would do is cover the sensor with propolis?
I mount the little black box on the outside and either drill a small hole for the probe and wire or simply cut a very shallow grove for the cable to lay in between box edges.
Yes ... it does that as well ... although I converted to polycarbonate crown boards fairly quickly and a quick look under the roof confirms the colony is alive.My use of these is really simple - in the wintertime it shows me they are still alive !!
Hi
.
They are sold stating 100 day battery life. Mine did that in the summer, but I would think they would die a bit quicker int he cold.
Some are stating 365 days, on CR2477 battery.
