MicroPython MLX90614

A MicroPython library for interfacing with a Melexis MLX90614 IR temperature sensor.

For example, the GY-906 module.

Examples

Copy the file to your device, using ampy, webrepl or compiling and deploying. eg.

$ ampy put mlx90614.py

Basic measurement

import mlx90614
from machine import I2C, Pin

i2c = I2C(scl=Pin(5), sda=Pin(4))
sensor = mlx90614.MLX90614(i2c)

print(sensor.read_ambient_temp())
print(sensor.read_object_temp())
if sensor.dual_zone:
    print(sensor.object2_temp)

Continuous measurement

import time
import mlx90614
from machine import I2C, Pin

i2c = I2C(scl=Pin(5), sda=Pin(4))
sensor = mlx90614.MLX90614(i2c)

while True:
	print(sensor.read_ambient_temp(), sensor.read_object_temp())
	time.sleep_ms(500)
