NL Sensor

Stream Nu Lambda Scientific sensors live, chart every reading, fit and export your data, and challenge yourself with the Walk the Graph motion activity.

NL Sensor turns your iPhone or iPad into a live dashboard for Nu Lambda Scientific Bluetooth sensors. Connect a sensor, watch the data stream in real time, analyze it on the spot, and export it — all on device, with nothing sent to the cloud.

MEASURE ANY SENSOR IN THE FLEET • Motion / distance, force / load, voltage, current, pressure, illuminance, and 3-axis magnetometers are detected automatically by name. • Metric cards show the current value and a stable 40-point average. • Set the sample rate from 1 to 100 Hz right from the app.

LIVE CHARTS BUILT FOR THE LAB • A smooth 10-second sliding window while you measure. • Pause to pan and pinch-zoom, show all data, reset, or clear. • Drag to select a region and get a least-squares linear fit (slope, intercept, R²) or statistics (mean, standard deviation, count). • Expand any chart to full screen.

MOTION, VELOCITY & ACCELERATION • Motion sensors add derived velocity (m/s) and acceleration (m/s²) charts, computed with smoothed derivatives.

WALK THE GRAPH • Turn distance-time graphs into a movement challenge: pick a target curve, walk to match it, and get a live score for how well your motion tracks the graph. Five graph sets from basic to creative.

TWO SENSORS AT ONCE • Connect two sensors and compare them on an XY chart that pairs their latest readings in real time.

EXPORT EVERYTHING • Export any chart, the XY data, or the entire session as CSV through the iOS share sheet.

PRIVACY • All measurements stay on your device. No account, no tracking, no data collection.

NL Sensor requires a compatible Nu Lambda Scientific Bluetooth sensor. A built-in demo mode lets you explore the app without hardware.
