This is the Gravity I2C supported Non-contact IR Temperature sensor which I recently got from the DFrobot. This is a medical-grade Non-contact temperature sensor and offers an accuracy of ±0.2˚C in a limited temperature range around the Human body temperature. As a standard, the MLX90614 is calibrated for an object emissivity of 1. I have seen guys completely ignoring the emissivity value when using the MLX90614 infrared temperature sensor. Let me first explain what is Emissivity and then I will practically explain what happens when you ignore the Emissivity value. Emissivity: Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface or a black body. A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with an emissivity value of 0 would be considered a perfect thermal mirror. For example, if an object had the potential to emit 100 units of energy but only emits 90 units in the real world, then that object would have an emissivity value of 0.90. In the real world, there are no perfect "black bodies" and very few perfect infrared mirrors so most objects have an emissivity between 0 and 1. Different objects have different emissivity values and when you ignore the emissivity value then you will end up getting the wrong temperature readings. As I said earlier, as a standard, the MLX90614 is calibrated for an object emissivity of 1. So, let’s say if you want to measure the temperature of a human body then you will need to recalibrate your MLX90614 non-contact infrared temperature sensor. Let me practically show you. ******************** DFRobot: https://www.dfrobot.com/ Amazon Purchase links: ********** Arduino Nano USB-C Type ( recommended): https://amzn.to/4ahGLdk ESP32 WiFi + Bluetooth Module for iOT Projects (recommended), more IO pins, improved speed, and supports a Lipo Battery: https://amzn.to/3v40DkE MLX90614 non-contact infrared temperature sensor https://amzn.to/3wcyNku SSD1306 Oled display Module https://amzn.to/3qiDhCp DS18B20 One-wire waterproof digital temperature sensor https://amzn.to/3tksppg 16×2 i2c LCD https://amzn.to/3ifHouD Other must-have Tools and Components: Top Arduino Sensors: https://amzn.to/3vZbnfM Super Starter kit for Beginners https://amzn.to/3cq56C5 Top Oscilloscopes https://amzn.to/3ctF3d8 Variable Supply: https://amzn.to/2PEAqE7 Digital Multimeter: https://amzn.to/2QGRPg1 Top Soldering iron kits: "best" https://amzn.to/39nqDtb Top Portable drill machines: https://amzn.to/3suQMh7 Jumper Wires: https://amzn.to/2NYPEDA 3D printers: https://amzn.to/3ruG1dt CNC Machines: https://amzn.to/3cuZWVv Electronics Accessories: https://amzn.to/3sueV7z Hardware Tools: https://amzn.to/3m9UhaN DISCLAIMER: This video and description contain affiliate links, which means that if you click on one of the product links, I will receive a small commission.
