Environmental Sensors and Presence Detection

Environmental sensors, presence detection, door contacts and low-frequency wireless endpoints are useful early candidates when assessed using measured light and duty cycles.

Key variables

Sampling interval, sensor wake-up, wireless transmission, installed illuminance and storage loss determine energy margin.

This is a scenario and engineering assessment, not evidence of a released product or deployment.

FAQ

Why assess average power first?

Harvested energy is continuous; storage buffers short peak events.
