Bees are best and probably only source of honey. If you have beehive at home, you know that it need taking care and monitoring of conditions. If you miss something your bees may swarm and migrate. So it is important to keep an eye on hive temperature and humidity. Marc has been working on beehive monitoring system that allows reading its temperature and humidity. He’s chosen DHT22 temperature and humidity sensor which is easy to interface to Arduino.
His intent is to expand project to do more than monitoring temperature. He wanted it to send SMS when hive parameters goes beyond threshold. Other planed features include measuring the weight of hive to determine the amount of honey; additionally there shall be entrance activity and buzz monitoring. Also movement detection near hive to prevent vandalism. But since summer is almost over, most of plans are left for winter to accomplish. To see whats already done you can head to github resources.
