SmartElex TMP102 Digital Temperature Sensor

SmartElex TMP102 Digital Temperature Sensor

The SmartElex TMP102 Digital Temperature Sensor is a compact and easy-to-use Temperature Sensor Module designed for accurate digital temperature measurement in Arduino, IoT, and embedded projects.

Unlike analog sensors, this Digital Temperature Sensor communicates directly over the I2C bus, delivering stable and noise-free readings with a fine resolution of 0.0625°C and accuracy of ±0.5°C.

It operates efficiently within a 1.4V to 3.6V range and includes onboard 4.7kΩ pull-up resistors for hassle-free I2C communication without level shifting.

With added Molex PicoBlade connectors, an address jumper for flexible I2C addressing, and standard 0.1″ pin spacing for breadboard compatibility, this module is ideal for temperature monitoring, automation systems, and low-power electronics projects.

Features:

• uses the I2C interface.
• I2C Address: 0x48 by default (three more addresses are also selectable).
• Resolution: 12-bit, 0.0625ºC.
• Typical temperature accuracy is 0.5ºC.
• 3.3 V sensor
• Supports up to four TMP102 sensors on the I2C bus at one time.
• 2 Molex PicoBlade Connectors
