Mlx90614 in Pwm mode

Hi everyone. I’m trying to figure out how to use 3 Mlx90614ESF-BAA infrared thermometer in PWM Mode.
Here is the schematic(i have not bought them yet). I have not found any tutorial about how to program it yet. Do you have any idea?

I’m trying to figure out how to use 3 Mlx90614ESF-BAA infrared thermometer in PWM Mode.

From what I see about the Mlx90614ESF-BAA sensor it is an I2C device or it can output the temperature with a voltage level using a PWM modulation or reading it precisely via I2C.So you must choose how you will “speak” to your sensor.
Note that they are different resolutions so choose carefully

The MLX90614 provides two methods of output: PWM and SMBus (i.e. TWI, I2C). The 10-bit PWM output provides a resolution of 0.14°C, while the TWI interface has a resolution of 0.02°C. The MLX90614 is factory calibrated in wide temperature ranges: -40 to 85°C for the ambient temperature and -70 to 382.2°C for the object temperature. The measured value is the average temperature of all objects in the Field Of View of the sensor. The MLX90614 offers a standard accuracy of 0.5°C around room temperatures.

This sensor has a fixed i2c adress so i cant use more than one if i communicate through i2c. Thats why im trying to figure out how to program in PWM Mode. About the resolution, 0.14C is fine for me.

So just read sensor output in ADC and retrieve your temp data ...
