Hardware Design
Description: This is a batteryless sensor based on the BQ25505 harvester chip and the LPC54102 microcontroller. This light-powered sensor node uses a traditional vision sensor to acquire images. These images can be processed by the LPC microcontroller, and the results can be broadcast using a BLE transceiver. To support intermittent computing, off-chip FRAM can be used. This device has multiple configuration options, and for certain applications, it can be configured to have a backup battery.
