![]() ![]() It also provides immunity against ambient light and sunlight. The MLX90614 has a built-in optical filter that cuts off visible and near-infrared light, reducing their effect on measurements. Both the ambient temperature and the object temperature have a resolution of 0.02☌ with a standard accuracy of 0.5☌ around room temperatures. Ambient temperature can be used to calibrate the data, but what we really need comes from object temperature measurements.īecause it does not have to touch the object being measured, it can sense a wider range of temperatures than most digital sensors: object temperature measurements range from -70 to 382.2☌, while ambient temperature measurements range from -40 to 125☌. The object temperature is the non-contact measurement ‘observed’ from the sensor, while the ambient temperature measures the temperature on the die of the sensor. The MLX90614 generates two temperature measurements: an object temperature and an ambient temperature. ![]()
