Usage Examples

Connect your sensor in following way:

• vin ↔ 3V
• gnd ↔ gnd
• scl ↔ gpio5
• sda ↔ gpio4

Now, to make 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)

To perform continuous measurement:

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

There are some useful properties:

• .dual_zone - set to True if the sensor has two thermopiles
• .ambient_temp - equivalent to read_ambient_temp(), also works for object and object2
