Sensirion STS4L – An Affordable Temperature Sensor for Your Application

The STS4L temperature sensor is the latest addition to the STS4x family. It offers a 20% cost reduction compared to the STS40-AD1B sensor, with only a slight compromise in accuracy. Its low power consumption of 0.4 µA and wide supply voltage range of 1.08 to 3.6 V make it an ideal choice for battery-powered applications.
