Temperature & Humidity

IDW-SD01 12-bit Temperature & Humidity Sensor

The 12-bit Temperature/Relative Humidity Smart Sensor is designed to work with all data loggers that accept Smart Sensors. All sensor parameters are stored inside the Smart Sensor, which automatically communicates configuration data information to the logger without any programming, calibration, or extensive user setup.

Measurement Range

Temperature: -40°C to 75°C (-40°F to 167°F)
RH: 0-100% RH at -40° to 75°C (-40° to 167°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

Accuracy
Temperature: +/- 0.21°C from 0° to 50°C (0.38°F from 32° to 122°F)
RH: +/- 2.5% from 10% to 90% RH (typical), to a maximum of +/- 3.5% including hysteresis at 25°C (77°F); below 10% and above 90% ±5% typical

Resolution
Temperature: 0.02°C at 25°C (0.04°F at 77°F)
RH: 0.1% RHNumber of data channels: 2
