Temperature sensor board SR-2904 (Temperature Sensor I2C)

The temperature sensor board SR-2904 is a high-quality digital temperature sensor board, providing I2C interface feature. This digital temperature sensor converts temperatures between -55°C and +125°C to a digital word. It provides an accuracy of ±1°C (maximum) from -10°C to +85°C. Connected to the Spectrah’s AD controller board through I2C, SR2904 transfers temperature data to AD controller board. The Spectrah’s AD controller board with UART port then sends temperature data through RS232 interface to host PC. User can see all the temperature value change on host screen.
