The concept of battery-less energy harvesting remote control is to create an extremely low power remote control that is compatible with the majority of existing systems. The built-in energy harvesting control circuit enables equipment to operate from energy harvesting power sources with only weak ambient energy. The RE01B microcontroller family is equipped with a powerful 32-bit CPU with extremely low power, an energy harvesting controller and Bluetooth® 5.0 (BT5.0).
Renesas' Lab on the Cloud is an online environment where Renesas solutions, including popular evaluation boards, winning combinations and software, are hosted in a remote lab that customers access and test online.
The built-in energy harvest control circuit in the RE01 MCU enables the equipment to operate with the energy harvested from ambient energy. The remote controller demo board can be operated properly by using small silicon solar cells (126µW) and a 1000µF capacitor to power the whole system. This demo can be used to remotely control a DVD player, as well as monitor the temperature and humidity with the HS3001 sensor. The capacitor voltage is charged using the built-in energy harvest controller (EHC) circuit in the RE01 MCU and can be observed in real-time on a GUI.
