SparkFun Digital Temperature Sensor – TMP102 I2C

Все о продукте

The TMP102 is an easy-to-use digital thermometer made by Texas Instruments. The TMP102 makes it easy to integrate a digital temperature sensor into your project. While other sensors use analog voltage to display temperature, the TMP102 uses the I ² C Arduino protocol to display temperature. It is a very convenient and easy-to-connect sensor.

The TMP102 is capable of measuring temperature with a resolution of 0.0625°C and an accuracy of 0.5°C. The sensor has a 4.7kΩ pull-up resistor for I ² C protocol communication and has an operating voltage range of 1.4V to 3.6V.

Features:

• ^I2C interface
• 12-bit, 0.0625°C resolution
• Average measurement error: ±0.5°C
• 3V sensor
• Supports up to four TMP102 sensors on the ^I2C interface simultaneously
