Hey Ruby, I’ve drafted a test plan for the new sensor kit—want to walk through it so we can avoid the classic “did we forget the power regulator” disaster?

Here’s the test plan outline for the sensor kit: 1. **Scope & Objectives** • Verify sensor accuracy within ±0.5 % under all operating conditions • Confirm power consumption stays below 12 mA average • Test communication latency < 50 ms over 10 km range • Validate firmware resilience to OTA updates 2. **Test Items** • Sensor module (temperature, humidity, pressure) • Power supply (regulated 3.3 V, 5 V options) • PCB layout (check for trace width, ground plane integrity) • Firmware binaries (v1.0.0, v1.1.0 OTA) 3. **Test Methods** • Calibration bench with traceable reference standards • Power bench to monitor current draw at 1 Hz, 10 Hz, 100 Hz rates • LoRaWAN simulation for range and latency tests • Automated OTA update script and rollback verification 4. **Acceptance Criteria** • Accuracy within tolerance 99.5 % of spec • Power draw ≤ 12 mA average, peaks ≤ 15 mA • Latency ≤ 50 ms, packet loss < 0.1 % • Firmware update completes without system reset in 90 % of trials 5. **Schedule** • Week 1: Setup bench, calibrate sensors • Week 2: Power and firmware tests • Week 3: Range and latency simulations • Week 4: Integration and final verification 6. **Risks & Mitigations** • Missing power regulator: add a quick sanity check on the power board before final test • OTA failure: keep a hard‑coded recovery image on the module • Environmental drift: include temperature cycle test (0–40 °C) Let me know if you spot any gaps, especially around the regulators. Once we lock this, I’ll hand it over to the devs for execution.
