Win an environmental and biometric SENSOR-PUCK!
I would like to use the SENSOR-PUCK to monitor bee hives.
As a hobbyist beekeeper I'm always interested in what is going on in my beehives. Opening the beehive to monitor the health of my bees is not always a good idea, especially if it is cloudy or rainy. Under these weather conditions the bees are quiet aggressive and most likely sting anybody opening the hive.
Wouldn't it be great to monitor the health of your bees by standing in front of your hive with your smart phone and getting vital data of your hive from the SENSOR-PUCK without opening the the hive and the risk of getting stung?
Temperature data and moisture level could give a hint if the bees are breeding. An additional added microphone could give some information on predicting the swarm period (if a small FFT would fit the EFM32). Further data could be collected from an digital weighing scale to get an indication of how much honey was collected or if the bees need additional feeding.
I see great potential in the SENSOR-PUCK as a ultra low power connected sensor platform and hope my idea of a bee hive monitor could became an reality through the utilization of the SENSOR-PUCK.

Review of the SENSOR-PUCK on Blog
The sensor puck is a nice peace of hardware in a tiny package. The features I'm mostly interested in are:
Additionally the schematics for the hardware is available as well as the source of the firmware running on the SENSOR-PUCK which is always good in case some things needed changing.
The sensor puck comes pre flashed with a demo application that is sending the sensor readings via BLE broadcasts. It is really easy to download and install the corresponding application form the android app store. As soon as the application is launched it shows the current readings from the selected SENSOR-PUCK:
The SENSOR-PUCK Users's Guide is very detailed and no question is left after reading it. Seeing the actual schematics of the SENSOR-PUCK is nice an adds greatly to the understanding of the capabilities of the SENSOR-PUCK beyond what the demo firmware provides.
5. Usage as a Beehive Monitor
The SENSOR-PUCK is a great demonstrator of the capabilities of SILICON LABS. The power consumption of the SENSOR-PUCK while measuring and broadcasting the sensor data (indicated by the green flashing LED) is average 1.5 mA which means according to the Users's Guide the battery on the SENSOR-PUCK will last approximately five days. Which is really great knowing the measurement is taken every second. So that makes approximately 432,000 measurements and bluetooth broadcasts on a single 3V coin cell battery. When it comes to beehives and environmental changes the update rate of 1 Hz is a bit of an overkill for the application as a beehive monitor. An update rate of about an hour would be sufficient which could mean a battery life of greater 60 days. I hope I can change the firmware to match my application needs and try the SENSOR-PUCK under some harsh conditions like the one in the picture below.
Thank you Silicon Labs for letting my try out this great product.
