SENSIRION - STS4L - Temperature Sensor I2C DFN4

STS4L is the latest addition to the STS4x family. It is 20% cheaper than the STS40-AD1B at the cost of slightly reduced accuracy. Low power consumption of 0,4 µA and supply voltage range of 1,08 to 3,6 V are ideal for battery-powered applications.

Features:

• Measurement range -40 to 125°C
• Accuracy ±0,4°C (typ.) @ 0 to 65°C
• Three measurement modes
  • High precision (high repeatability, 3 sigma=0,04°C)
  • Medium precision (medium repeatability, 3 sigma=0,07°C)
  • Low precision (low repeatability, 3 sigma=0,1°C)
• Three I2C addresses, STS4x-A (0x44), STS4x-B (0x45), STS4x-C (0x46)
• Communication speeds up to 1 MHz
• Supply voltage 1,08 to 3,6 V
• Average supply current at 3,3 V and one measurement per second
  • o 2,2 uA (high repeatability)
  • o 1,2 uA (medium repeatability)
  • o 0,4 uA (low repeatability)

Applications:

• The STS4x is ideally suited for air quality control and thermostats. It can also serve as an alternative to PTC thermistors, such as the popular but discontinued NXP KTY81 and 82 series.
