The Sparkfun Melexis MLX90614ESF-BAA is a remarkable infrared thermometer that offers non-contact temperature sensing. With an internal 17-bit ADC and a powerful DSP, this device takes accuracy and resolution to a whole new level. It is perfect for a wide range of applications, such as body temperature measurement and movement detection.The MLX90614 offers two types of output: PWM and SMBus (also known as TWI, I2C). The PWM output is 10-bit and provides a resolution of 0.14°C, while the TWI interface boasts a resolution of 0.02°C. This thermometer is factory calibrated for wide temperature ranges: -40 to 85°C for ambient temperature and -70 to 382.2°C for object temperature. The measured value is the average temperature of all objects within the sensor's field of view. The MLX90614 offers a standard accuracy of 0.5°C around room temperatures.The MLX90614 device is housed in an industry standard TO-39 package, and the version carried by Sparkfun operates on 3V.Features: * Compact size and cost-effective * Easy to integrate into different applications * Factory calibrated for wide temperature range: * -40 to +85°C for sensor temperature * -70 to +380°C for object temperature * SMBus compatible digital interface * Customizable PWM output for continuous reading * High accuracy of 0.5°C over wide temperature range (0 to +50°C for both Ta and To) * Measurement resolution of 0.02°C * Available in single and dual zone versions * Simple adaptation for 8 to 16V applications * Power saving mode * Various package options for versatile applications and measurements * Automotive grade Documents: * Hookup Guide * Datasheet * MLX90614 Product Information * bildr blog - MLX90614 * GitHub (Library) https://elecena.pl/product/27742928/sparkfun-infrared-thermometer-mlx90614 2025-01-23 https://elecena.pl/product/27742928/sparkfun-infrared-thermometer-mlx90614 2026-02-23
