NCIR Temperature Sensor Unit (MLX90614)

Description

NCIR featured with built-in infrared sensor MLX90614. It can be used to measure the surface temperature of a human body or other object.

Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. Because it doesn't have to touch the object it's measuring, it can sense a wider range of temperatures than most digital sensors: from -70°C to +380°C! It takes the measurement over an 90-degree field of view so it can be handy for determining the average temperature of an area.

Connect with M5Core via GROVE A IIC(0x5A).
