PyMLX90614

Python library for MLX90614 infrared temperature sensors, using smbus2. Compatible with Python 2 and 3.

You might need to enter this command on your Raspberry Pi:

sudo su -c 'echo "Y" > /sys/module/i2c_bcm2708/parameters/combined'

Consider putting it in /etc/rc.local so it's executed each bootup

Usage

First, ensure the device is available on the i2c bus:

$ sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- 5a -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Within Python, the device can be used like this:

from smbus2 import SMBus
from mlx90614 import MLX90614

bus = SMBus(1)
sensor = MLX90614(bus, address=0x5A)
print sensor.get_amb_temp()
print sensor.get_obj_temp()
bus.close()

Troubleshooting

Older versions of this package used different names for the ambient and object temperature methods. If you get an error like: AttributeError: 'MLX90614' object has no attribute 'get_ambient'. You might need to change any instances of get_ambient to get_amb_temp and any instances of get_object to get_obj_temp.
