Create Your Own Solar-powered Beacon For IoT


Now IoT developers can easily design tiny solar-powered IoT devices which can harvest energy from the sun or indoor lights and operate without a battery making them ideal to monitor environmental conditions in smart home, commercial building, factory and agriculture settings.

The tiny, solar-powered sensor beacon, which is 25 mm in diameter, can sense the temperature and humidity around its location and transmit the data using wireless BLE connectivity to their surrounding environment.

The new 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-BLE PRoC 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.

“Our solar-powered BLE sensor beacon reference design kit features robust, low-power sensing and wireless connectivity in a small form factor that can be easily deployed for more than a decade with no maintenance costs, addressing the most significant design challenges facing the expected rapid growth of industrial IoT devices,” said Kiyoe Nagaya, vice president of the Analog Business Unit at Cypress.

Also included in the kit is a Cypress BLE-Beacon app for iOS, Android and PCs, for users to receive and visualize sensor data transmitted by the sensor beacon as a 2D/3D graph visualization or to export the data.

Compact, Cost-effective Modules For Industrial Power Applications

The S6AE103A Energy Harvesting chip is claimed to operate with startup power of 1.2uW and consumption current of 280nA, maximizing the power available for the sensing, processing and communications functions of a target application.

The Cypress CYALKIT-E02 Kit can be pre-ordered for $49. Cypress also offers the CYALKIT-E03 expansion pack, which includes five solar-powered BLE sensor beacons, for $99. Both the kits will be available in July 2016.
