The light temperature sensor board SR-2907 is a dual functional sensor board for temperature and brightness detection. This product combines an integrated ambient & infrared light sensor and a high quality digital temperature sensor, providing I2C interface feature. Connected to the Spectrah’s AD controller board through I2C, SR2907 transfers temperature and light data to AD controller board. The Spectrah’s AD controller board with UART port then sends light and temperature data through RS232 interface to host PC. User can see all the light and temperature value change on host screen.
