This sensor measures temperature and humidity in a volume and gives the temperature below which the water vapor in that volume of air (at a constant barometric pressure) condenses into liquid water (the dew point). *Requires connection hardware, sold separately. Experiment Duration: 1 second to 31 days. Operation Modes: Range | ADC Resolution | Resolution. Max Sample Rate (S/sec): -114.0 to 109.0 °C, 12 bit, 0.1 °C, 100, -182.0 to 229.0 °F, 12 bit, 0.1 °F, 100.
