Title

Temperature Sensor

TI Item Name

STEMKT/AC/F

Description

Uses a thermistor to measure ambient temperature. The resistance of thermistor changes based on ambient temperature. This resistance value alters the output of a voltage divider which is measured by the TI-Innovator™ Hub and converted to a temperature value in centigrade degrees. The operating range is -40 to 125°C , with an accuracy of 1.5°C . This sensor is not waterproof and cannot be submerged.
