Joel_E_B SHT15 Overview
The SHT15 is an easy to use, highly accurate, digital temperature and humidity sensor. All you need is two lines for 2-wire communication, and you’ll have relative humidity and temperature readings to help you sense the world around you!
Features you should know about this sensor:
- Operating Voltage: 2.4V min - 5.5V max
- 2 factory calibrated sensors for relative humidity & temperature
- Digital 2-wire interface (Not I2C, but similar)
- Measurement range: 0-100% RH
- Absolute RH accuracy: +/- 2% RH (10…90% RH)
- Repeatability RH: +/- 0.1% RH
- Temp. accuracy: +/- 0.3°C @ 25°C
- Precise dewpoint calculation possible
- Fast response time
- Low power consumption (typ. 30 µW)
- Here’s the datasheet
This sensor is ideal for environmental sensing and data logging and can be used in applications ranging from a weather station to a humidor control system.
