High Precision Humidity Sensor SHT15

The SHT15 digital humidity and temperature sensor is fully
calibrated and offers high precision and excellent long-term
stability at low cost. The digital CMOSens® Technology
integrates two sensors and readout circuitry on one single chip.

Features

• 2 sensors for relative humidity & temperature
• Precise dewpoint calculation possible
• Measurement range: 0-100% RH
• Absol. RH accuracy: +/- 2% RH (10...90% RH)
• Repeatability RH: +/- 0.1% RH
• Temp. accuracy: +/- 0.3°C @ 25°C
• Calibrated & digital output (2-wire interface)
• Fast response time < 8 seconds 
• Low power consumption (typ. 30 µW)
• Low cost
• High precision sensor at low cost
• Leading CMOSens® Technology for superior long-term stability
• Very easy-to-use due to calibration & digital 2-wire interface

Applications

• Precise data logging
• Transmitters
• Automation & process control
• Building control and HVAC
• Test & Measurement
• Medical
