The STS3x is high-accuracy digital temperature sensor series. The STS3x temperature sensor utilizes the industry-proven technology and wins over users with its increased intelligence, reliability, NIST traceability and improved accuracy specifications. There are also automotive grade versions available.
The STS3x temperature sensor gives a fully calibrated, linearized, and supply-voltage-compensated digital output and has an outstanding accuracy of up to +/-0.1°C. There are three versions available: the standard version, STS31, guarantees an accuracy of ±0.2°C over a temperature range of 0°C to 90°C, while the low-cost version, STS30, has an temperature range of 0°C to 65°C. The high-end version STS35 is the most accurate temperature sensor available with an accuracy of ±0.1°C over a temperature range of 20 to 60°C.
