Infrared Thermometer
High precision IC with low power consumption peripheral circuit can measure temperature without contact via thermopile infrared sensor.
Program overview
In recent years, non-contact infrared temperature measurement has developed rapidly. The performance and functions have greatly improved. The variety of applications continue to increase and expand. Our SD8000 series infrared thermometer solution, the temperature is measured by the thermopile infrared sensor and the signal is transmitted to the IC, which is displayed by the LCD. This thermometer has simple circuit, few peripheral components, low power consumption, accurate and quick reading, non-contact type, safe use and long service life, and response time is fast.
Program advantages

  • Long term reliability

  • Single chip solution, few peripheral components needed and high performance to cost ratio

  • Built-in high precision ADC, suitable for weak signal measurement
