Say it to PAL

“Keep a precise log of the temperature.”

The code PAL writes

p.onSensorChange('qwiic-tmp117', 'temperature', (temp) => {
  p.log(`Temperature: ${temp.toFixed(4)}°C`);
});
await p.waitUntilStopped();

When to pick it

Lab-grade precision (±0.1°C).

About it

A precision temperature sensor meeting NIST standards for traceability. Accurate to ±0.1°C across -20°C to 50°C, making it suitable for laboratory use, medical devices, and precision industrial applications. Can serve as a calibration reference for other temperature sensors.
