Introduction: Temperature measurement can be divided into two types: contact and non-contact. Contact measurement needs the testing object and the sensor to reach thermal equilibrium for accurate results, which may lead to longer response times and inaccuracies due to ambient temperature. On the contrary, non-contact measurement uses infrared radiation, doesn't require direct touch, and can provide quick and accurate readings. In recent years, non-contact measurement has been widely used in medical, environmental monitoring, home automation, automotive electronics, aerospace, and military fields. Our latest MLX90614 infrared temperature measurement module detects infrared radiation energy and wavelength distribution to measure surface temperature. The IR temperature probe includes an optical system, photoelectric detector, amplifier, signal processing, and output module. The optical system collects infrared radiation, which is then converted into electrical signals on the photoelectric detector. After being processed by the amplifier and signal - processing circuit, the signal is turned into a temperature value. The MLX90614 is self - calibrating and has a low - noise amplifier integrated into the signal - processing chip, which is a 17 - bit ADC and DSP device, ensuring accurate and reliable results.

Using this non - contact infrared temperature sensor is quite easy. First, connect the sensor to your Arduino using the provided JST PH2.0 4 - Pin cable following the interface line sequence of VCC, GND, SCL, SDA. Make sure the operating voltage is within the range of 3.3V - 5V. Once connected, power on the system and the sensor will start measuring the temperature. You can view the results on your Arduino's display or through other connected devices. When using, avoid exposing the sensor to extreme temperatures outside the - 70.01°C to + 382.19°C range, as it may affect the measurement accuracy. Also, keep the optical system of the sensor clean to ensure it can collect infrared radiation properly. For maintenance, check the cable connections regularly to make sure they are secure. If there are any signs of damage to the sensor or cable, replace them promptly.
