Sensor that uses IR to measure temperature. It works in the range from -70 °C to 380 °C for object temperature or -40 °C to 85 °C for sensor temperature. It communicates via the I2C bus (SMBus, TWI) with a resolution of up to 0.02 °C or interface PWM - 0,14 °C. It has a built-in 17-bit ADC converter that provides the high accuracy of the measurement (below 0.5 °C). The supply voltage ranges from 3.0 V to 3.6 V. This version has increased accuracy in the medical range: from 20 °C to 40 °C.
