O-Level Physics Data Logger & Sensor Playbook
Study guide
TL;DR
SEAB’s 2026 O-Level Physics syllabus says Paper 3 candidates are expected to be “familiar with the use of data-loggers” and Planning may include them (Apparatus list, 6091 2026 syllabus PDF).
Practise with smartphone sensors, school-issue interfaces (Vernier, PASCO, Fourier), and browser simulations so MMO/PDO habits transfer straight into the practical.
Always log units, sampling intervals, and start/end conditions; download raw CSVs for graphing drills.
Keep the full Paper 3 practical roadmap in our O-Level Physics Experiments hub.
1 | Core sensors mapped to Paper 3 experiment families
| Skill strand | Experiment context | Sensor / tool | Home-friendly option | Pro tip |
| Mechanics MMO | Timing free-fall, pendulum, trolley + light gate | Vernier Photogate, PASCO Smart Timer | PhyPhox “Acoustic Stopwatch”, Physics Toolbox Suite “Pendulum” | Record at least 10 oscillations; export CSV to cross-check average period. |
| Mechanics PDO | Velocity-time tracking | Vernier Go Direct Motion, PASCO Sparkvue Motion | iPhone/Android video at 240 fps + Tracker video analysis | Calibrate distance using a known marker; note frame interval in tables. |

Practical course completion-record note
For practical, lab, and experiment courses, Eclat Institute maintains centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.
- For SEAB private-candidate declarations, the key evidence is the centre's attendance or completion record, not a government-issued certificate.
- This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
- Recognition (if any) is determined by the receiving school, institution, or employer.
- For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or attend a practical course and complete it before the practical paper date.
