In recent years, the demand for temperature measurement has increased. The SD5000 series is designed as a digital thermometer solution. The integrated temperature sensor can directly convert the temperature into a serial digital signal while measuring the temperature. Temperature displays on the LCD or LED after the IC processes the signal. The thermometer has a strong anti-interference ability, high temperature measurement accuracy, convenient reading, no calibration, convenient debugging, and easy development. It can be used in industrial and household environments.
