Background


Before moving to our apartment, there was a wetland pond behind our backyard. A Wyze Cam 3 was mounted above the shed to observe wildlife activity. The camera required a 10,000 mAh power bank, which barely lasted ~24 hours of continuous use before needing a swap.

The goal became powering the camera only on demand — when a viewer clicks the "videofeed" link on the hosted website. Clicking the Observations II link returns the viewer to the main menu.

A FreeRTOS-based Transmitter (TX) sends commands over LoRa to a deep-sleep Receiver (RX) that controls camera power via a KY-002S bi-stable latching switch.
