Cypress – Create a Tiny Solar-Powered IoT Wireless Sensor Node with the Lowest Power Energy Harvesting BLE Solution


The Solar-Powered BLE Sensor Beacon Reference Design Kit (RDK) is designed to help you create tiny, solar-powered IoT devices with BLE wireless connectivity. The RDK comes with a Solar BLE Sensor, as well as a BLE-USB Bridge and Debug Board. The Solar BLE Sensor is based on Cypress’ Energy Harvesting Power Management IC (PMIC) S6AE103A and EZ-BLETM PRoCTM Module (CYBLE-022001-00).

The sensor is designed to harvest energy from the sun or indoor lights and operate without a battery. The BLE-USB Bridge and Debug Board can be connected to a host (PC) that receives sensor data transmitted by the Solar BLE Sensor. The BLE-USB Bridge and Debug Board also help with on-chip debugging for the Solar BLE Sensor via an easy to use USB interface. This tiny RDK is a fully-loaded connectivity solution that is compact, battery- free, and BLE-ready. Cypress also offers an expansion pack CYALKIT-E03 that includes five Solar BLE Sensors.

Tiny, But Powerful Solar BLE Sensor
The Solar BLE Sensor transmits temperature and humidity data using the BLE broadcasting mode. The Solar BLE Sensor is ultra-low power and works with just solar energy. The solar energy is managed by our versatile Energy Harvesting PMIC S6AE103A.

Cypress® BLE-BeaconTM App
The Cypress BLE-Beacon app works across iOS, Android, and PCs. The app is designed to receive and visualize beacon signals or sensor data that is transmitted by the Solar BLE Sensor. The app shows you real-time data as 2D/3D graphs. The logging data can be exported to CSV file for offline access and analysis.
