TMP102 Digital Temperature Sensor Module

The TMP102 device is a digital temperature sensor ideal for NTC/PTC thermistor replacement where high accuracy is required. The device offers an accuracy of ±0.5°C without requiring calibration or external component signal conditioning. Device temperature sensors are highly linear and do not require complex calculations or lookup tables to derive the temperature. The on-chip 12-bit ADC offers resolutions down to 0.0625°C. The module (HCMODU0100) provides header pins for power (3.3V), and to its digital I2C interface including bus pullup resistors. 

PLEASE NOTE: This module does not include an on-board regulator. Do not power it above 3.6V otherwise you will cause permanent damage. 




Features:

• Accuracy Without Calibration:
– 2.0°C (max) from –25°C to 85°C
– 3.0°C (max) from –40°C to 125°C
• Low Quiescent Current:
– 10-μA Active (max)
– 1-μA Shutdown (max)
• Supply Range: 1.4 to 3.6 V 
• Resolution: 12 Bits
• Digital Output: I2C interface Compatibility
