Low-Power Sleep Patterns for Arduino Field Nodes

Battery-powered Arduino projects fail in two ways: unstable wake cycles and hidden current draw. I start by listing every component in active and sleep state, then I budget power in milliamp-hours before writing firmware.

LoRa Sensor Node Power Budgeting in Practice

LoRa is chosen for range and efficiency, but many nodes still miss battery targets by a large margin. The reason is usually poor budgeting assumptions and missing field validation.
