Interested in temperature-sensing applications? Elektor and Mouser Electronics want to test your knowledge about the ON Semiconductor RSL10-COIN-GEVB ultra-low power temperature sensor beacon. Take the RSL10 Quiz for your chance to win!

The RSL10-COIN-GEVB

The ON Semiconductor RSL10-COIN-GEVB is a coin cell-operated, ultra-low power Bluetooth beacon. The board incorporates a temperature sensor, NCT375, and an RSL10, the industry's lowest-power Bluetooth 5 SoC. With the included CR2032 coin cell battery and an advertising packet being sent every 2 seconds, the device lasts over 6 years! The beacon follows Eddystone, an open beacon format from Google. A web URL and ambient temperature data embedded in the advertising packet can be read using Beacon Scanner or other freely available beacon scanning apps from the Android and iOS app stores.
