Abstract: We are developing a thermal imager using an infrared thermometer MLX90614. This sensor works on the principle of infrared radiation. It is a non-contact type measurement device. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation (blackbody radiation) emitted by the object being measured [1]. The novelty of this project is that we have made it economical compared to the thermal imagers available in the market. We used a single MLX90614 sensor and made it to move on the vertical and horizontal axis using a Pan-Tilt servo motor mechanism. The mechanism was set up in such a way that it would cover the whole object which is being scanned [2]. Also, we attached laser so that non-contact point being measured can be known and the temperature reading of the point are made available on the 16*2 LCD. In addition to this, ELP 2.1mm lens wide angle webcam with low illumination camera for day and night vision compare the original picture of the object with the thermal image of the same [14]. We also plotted live graph of the temperature detected by the IR sensor MLX90614 on MATLAB. We acquired the data by Fluke Thermal Imager and by our system. After that we compared the data acquired from both the sources.
