Description The MLX90614 is an infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C. The user can configure the digital output to be pulse width modulation (PWM). As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120°C, with an output resolution of 0.14°C. Application Temperature sensor related. Product information Small size and low cost Easy to integrate Factory calibrated in wide temperature range: -40 to 125°C for sensor temperature and -70 to 380°C for object temperature High accuracy of 0.5°C over wide temperature range (0..+50 C for both Ta and To) Medical accuracy of 0.1°C in a limited temperature range available on request Measurement resolution of 0.02°C Single and dual zone versions SMBus compatible digital interface for fast temperature readings and building sensor networks Customizable PWM output for continuous reading Available in 3V and 5V versions Simple adaptation for 8 to 16V applications Power saving mode Different package options for applications and measurements versatility Automotive grade Technical Document GY-906-BAA Tested Measurement Distance +/- 2CM GY-906-BCC Tested Measurement Distance +/- 8-10CM Condition New Type Voltage Regulator Model Number MLX90614ESF-DCI Application Other Operating Temperature -40~85 Degrees Celsius Supply Voltage 3~5V Dissipation Power MLX90614ESF-DCI Sensor Module Package TQFP Comminication protocol : I2C References Tutorial with ESP32 http://www.esp32learning.com/code/esp32-and-mlx90614-infrared-thermometer-example.php Details https://www.melexis.com/en/product/MLX90614/Digital-Plug-Play-Infrared-Thermometer-TO-Can#
