A signal-level STEM lesson comparing cadence and torque inputs, including latency, filtering, plausibility checks and firm classroom safety limits.
Motion vs Rider Effort: An E-Bike Sensor STEM Lesson Read More
Map the detection zone, test still occupancy and false triggers, then measure entry and absence latency before an mmWave sensor controls a room.

Matter-over-Thread makes smart-home setup cleaner, but sensor placement and mesh planning still decide whether automations behave reliably.
Matter-over-Thread Sensors Need Placement Discipline Before They Feel “Smart” Read More
Robot sensor problems often start at the connector. JST-style plugs and screw terminals solve different wiring problems, and each can fail if used in the wrong place.
JST or Screw Terminal? Robot Sensor Wiring Fails When Connectors Don’t Match the Job Read More
Photogates and phone video can both teach sports technology, but they measure different things. The best classroom setup starts with the question.
Photogate Timing or Phone Video? STEM Sports Tech Projects Need the Right Measurement Tool Read More
Torque and cadence sensors change how an e-bike controller interprets rider input; maker garages should diagnose assist feel with sensors, wiring, calibration, and safety in mind.

Bluetooth Channel Sounding can make proximity projects more rigorous, but only if students treat ranging as a measurement problem with calibration, logs, and failure cases.
Bluetooth Channel Sounding Gives Maker Labs a Better Proximity Test to Study Read More
Sports timing gates are more than training gadgets when students treat them as a measurement system: sensors, alignment, reaction time, calibration, uncertainty, and data quality.
Sports Timing Gates Can Turn Speed Drills Into a Real STEM Measurement Lab Read More
Sports wearables can become useful STEM projects when students stop treating the dashboard as truth and start testing sensor placement, sampling, calibration, and missing data.
Sports Wearable Data Is a STEM Project When Students Test the Sensors Read More
