I use data loggers from Thorsten Gurzan (www.beelogger.de) to collect climate data from beehives. In particular, the Beelogger Solar SD is in use. This special version of the Beelogger Solar is not yet available on the website, because – with my cooperation – it is still under development. However, the manual and a program code with standard setup will be available shortly.
Beelogger Solar SD
- Waterproof housing, suitable for outdoor use, with screw-on device
Each measuring station contains 3 combined sensors for humidity and temperature, with an accuracy of ±0.5°C or ±3%.
- Equipped with a real-time clock, i. e. the data is written with a time stamp. This real-time clock also records the temperature in the housing.
- The card in the SD card holder can be removed at any time. If it is pushed back in again, writing continues automatically.
- The sensors are calibrated and adjusted at 75% relative humidity. Experience has shown that relative humidity between 50 and 90% is recorded fairly accurately in hives during the different seasons. In addition, the range between 70 and 80% is particularly interesting, as the risk of mould increases considerably from this humidity.
- 3400mAh battery and a small solar panel ensure maintenance-free operation. Combined with the extremely low power consumption, the unit is likely to work without problems even in the forest and in winter with a fully charged battery.
- Power consumption is likely to be unique. After a measurement, the software sends all components to sleep. In this sleep phase, the unit consumes 8-10µA, which is almost nothing. After a freely adjustable interval, the complete unit is “woken up”again for the next measurement.
- The unit can theoretically record maintenance-free for years.
- Modifications and extensions are possible.
