20011957-00

20011957-00 is a miniature digital temperature sensor that provides factory-calibrated highly accurate temperature data. This device contains a durable temperature sensor element, A/D converter, and microcontroller to manage data communications via an I²C interface. This package is very small and has low thermal mass which provides a quick response to temperature changes. The operating and sleep currents are extremely low making this sensor ideal for mobile and battery power applications. Applications include industrial control, replacement of Precision RTDs, thermistors and NTCs, heating/cooling Systems, HVAC, medical probes and patient monitoring, weather stations, fitness watches and wearables, and consumer appliances.
