Product Description:
The TMP102 Digital Temperature Sensor Module is a high-precision, low-power temperature sensor designed for accurate and reliable thermal measurement in compact electronic systems. Featuring 12-bit resolution and I²C (TWI) digital communication, this module offers an easy and efficient way to measure temperature without requiring analog-to-digital conversion.
The TMP102 provides 0.0625°C resolution with typical accuracy of ±0.5°C across its primary temperature range. It’s an excellent choice for battery-powered or low-energy systems thanks to its ultra-low power consumption — only 10 µA in active mode and 1 µA in shutdown mode.
Built-in filtering capacitors and pull-up resistors ensure signal stability and ease of integration with Arduino, Raspberry Pi, ESP32, STM32, and other microcontroller platforms.
