Define sensing and connection behavior, compare power rails and complete battery cycles, then validate recovery and retain measured device results.
Write the sensing interval, data volume, communication path and required behavior when connectivity or power fails. Include startup, transmission, retry, receive, idle and sleep states. Decide which data must survive a restart and which behavior will be checked in the prototype.
Record sensor, controller and radio voltage ranges and their measured or documented rail currents. Compare supply rails and regulators across the source’s full range. Check startup sequencing, radio current pulses and reset thresholds before assuming a nominal battery voltage is sufficient.
Use battery-terminal current for a current model, or usable battery watt-hours with regulated-load efficiency per state for an energy model. Include excluded quiescent overhead once and keep an explicit reserve. Compare normal connectivity with a separately saved retry or prolonged awake case.
Assemble the low-voltage prototype to the component instructions. Verify sensor readings, message delivery, bounded retry behavior and recovery after a controlled restart. Record firmware version and configuration. Review credential storage, update behavior and data minimization for the actual deployment.
Capture representative sleep, sensing and radio activity at the correct electrical point with suitable bandwidth and burden voltage. Measure the time spent in each state and compare controlled good-network and unavailable-network conditions. Check reset behavior and usable energy at the intended cutoff.
Export the measured energy cases, state timings and recovery results with the device’s hardware/firmware revision and deployment conditions. Record the actual battery care and service method. Revisit the budget after changing reporting frequency, radio coverage, sensors or update behavior.
Structure a complete battery-current or regulated-energy cycle including retry and sleep states. · Compare complete normal and retry duty cycles without mixing rail current bases. · Replace nominal state currents and times with measured cycle values. · Save the final measured cycle and a degraded-connectivity comparison.
Check continuous and radio-pulse rail demand against the selected source. · Recheck radio and restart current events measured during integration.
Compare regulator input/output envelope and applicable LDO dropout.
Record the chosen charge window and its capacity basis where SOC is used.
Keep an integration matrix with expected behavior, observed result and firmware revision. · Retain deployment configuration, acceptance results and follow-up changes.
Check a remote DC lead or connector path when its drop affects the device.

Complete load profiles and conversion conditions matter when a device spends most of its time asleep.
Choose supply regulation using the full input and load range.
Repeated connection attempts can keep a device awake much longer than a successful laboratory cycle.
Compare battery estimates before and after a reporting interval or firmware change.
