Frequently Asked Questions

What is the operating voltage range for this Digital Temperature Sensor 2.0 module?

The module's core sensor IC, the TMP102, operates from 1.4V to 3.6V. The module itself is designed to be compatible with 3.3V and 5V logic systems commonly used with microcontrollers like Arduino and Raspberry Pi, with 5V-tolerant I/O pins.

How do I connect and communicate with this sensor using a microcontroller?

The sensor uses a standard I2C (also SMBus compatible) two-wire interface. Connect the module's SDA and SCL pins to your microcontroller's corresponding I2C pins, along with VCC (3.3V recommended) and GND. You can then use standard I2C libraries to read temperature data. Up to four sensors can share the same I2C bus with different addresses.

What is the accuracy and resolution of the temperature readings?

The sensor provides a high digital resolution of 0.0625°C, allowing you to detect very small temperature changes. Its typical accuracy is ±0.5°C within its specified operating range of -40°C to +125°C, making it suitable for precise measurement applications.

Is this module compatible with the Arduino and Raspberry Pi platforms?

Yes, it is directly compatible. The standard I2C interface is supported by both Arduino (via the Wire library) and Raspberry Pi (via I2C bus). Its Crowtail connector also allows plug-and-play use with Elecrow's Crowtail base shields for Arduino, simplifying the wiring process.
