MLX90614 With Heating Plate

In this blog, I will be using a heating plate to test for the distance to spot ratio of MLX90614 without lenses, with a copper lens hood and Fresnel Lens.

MLX90614 Distance to Spot Ratio

Distance to spot ratio (D:S) is the ratio of the distance between sensor and target size. The object should completely fill the FOV of the sensor.

MLX90614 Distance Dependency

Temperature readings vary as object moves away from MLX90614. The distance dependency can be reduced with lens hood and Fresnel lens.

Arduino With MLX90614 and OLED Display

OLED display is an extremely handy way of interfacing sensor readings. I2C communication protocol with only four wires to hook up the OLED.

MLX90614 Voltage Compensation

Any voltage lower or higher than 3V might introduce temperature errors into MLX90614. A voltage compensation equation can solve the errors.

MLX90614 Infrared Temperature Sensor Tutorial

Measure the temperature with Arduino and contactless Infrared temperature sensor, the MLX90614 without any physical contact with the object.
