In addition, a simple GUI can be implemented via capacitive touch or push button(s), and/or a low power LCD (i.e., eInk) to display local sensor values and enter data. A more sophisticated GUI may also be achieved via a master actuator, IP gateway or smartphone. A real-time clock (RTC) could easily be added to switch between different operation modes, depending on the day, time, holiday, etc. All RTCs could also be synchronized within the system.
System Benefits
- The RX23W MCU enables Bluetooth 5 mesh communication
- The energy harvesting controller, the RE01 series, can be used for power supply. It combines the control of charging and discharging dedicated capacitors and/or rechargeable batteries of different sources with a powerful Arm® core MCU. These harvesters could be one of the following:
- Solar cell (i.e., using the natural or artificial room lighting)
- Thermal harvester (e.g., from a radiator or hot pipe)
- Vibration harvester (e.g., from machines/motors)
- RF harvester (i.e., taking away some of the near field energy from a close-by RF transmitter)
