Sensor detects thermal radiation, measures temperature without contact

Melexis has developed a FIRray sensing device, which employs non-contact temperature measurement technology to create a cost-effective thermography solution.

Dubbed MLX90620, this 16 x 4 element far infrared (FIR) thermopile sensor array covers a -20°C to 300°C temperature range. The MLX90620 produces a map of heat values for the target area in real time, avoiding the need to scan the area with a single point sensor or use an expensive microbolometer.

The MLX90620 can simplify thermal imaging systems by immediately capturing 64 pixel images in 2D, thus keeping the price point in the range needed for high volume, low cost applications. By integrating an amplifier and ADC in every pixel, the array offers an adjustable frame rate from 0.5 Hz to 64 Hz. Accuracy levels of ±1.5°C are maintained when operating in the 0°C to 50°C range. Two field of view (FoV) options are available 60º x 15º and 40º x 10º.

A high speed I²C compatible digital interface and a triggered mode for synchronization with a control unit mean that the MLX90620 can be used individually or combined in multiple devices to form an array with a larger imaging resolution.   

Key highlights:

• Small size, cost effective 16X4 pixel, thermal array
• Active thermopile pixel technology for fast readout Easy to integrate
• Factory calibrated in wide temperature range: -40 to 85 °C for sensor temperature and -20 to 300 °C for object temperature. 2 Field Of View options: 60X15degrees or 40X10degrees
