Temperature measurement can be divided into two main types: contact and non-contact. Contact measurement only gives accurate readings when the testing object and the sensor reach thermal equilibrium. This often means longer response times and inaccurate readings due to ambient temperature. On the other hand, non-contact measurement uses infrared radiation to measure temperature without direct touch. It provides 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 applications. Our latest MLX90614 infrared temperature measurement module detects infrared radiation energy and wavelength distribution to measure surface temperature. The IR temperature probe has an optical system, photoelectric detector, amplifier, signal processing, and output module. The optical system collects infrared radiation in its field of view, which is then converted into electrical signals on the photoelectric detector. After processing 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. The 17-bit ADC and DSP chip ensures accurate and reliable results. The SEN0263 (MLX90614-DCI) with a small field of view (FOV = 5°) is ideal for industrial applications with longer detection distances. For general applications, you can choose the SEN0206 (MLX90614-BCC). Specification: Model: MLX90614-DCI; Operating Voltage: 3.3V - 5V; Operating Current: 1.2mA; Temperature Range: -70.01℃ to +270℃, (0.01 ℃ resolution); Interface Type: I2C; Interface Line Sequence: VCC, GND, SCL, SDA; FOV: 5°; Dimensions: 31.5*18 mm/1.24 x 0.7 inches; Weight: 15g.

Using this temperature sensor is quite easy. First, connect it to your device following the interface line sequence of VCC, GND, SCL, and SDA. Make sure the operating voltage is within 3.3V - 5V. When measuring temperature, point the sensor at the object you want to measure. For industrial applications with longer detection distances, the SEN0263 (MLX90614-DCI) is a great choice because of its 5° field of view. For general uses, you can go for the SEN0206 (MLX90614-BCC). Keep in mind that the sensor works best when it's not affected by strong ambient temperature changes. Don't expose it to extreme temperatures outside the -70.01℃ to +270℃ range. To maintain the sensor, keep it clean and dry. Avoid physical damage to the optical system and the detector. Check the connections regularly to ensure they are secure. If you have any problems, refer to the product wiki or other available documents for more help.
