The TMP100 Temperature Sensor Module provides accurate digital temperature readings over I2C, making it ideal for environmental monitoring, thermal protection, and thermostat control projects. It supports configurable resolution from 9 to 12 bits and works with both 3.3V and 5V systems via an on-board voltage selector switch.

With a configurable I2C address (up to 8 devices on one bus) and a simple pin header interface, it's easy to integrate with Arduino, Raspberry Pi, and other microcontrollers.
