MLX90614 temperature sensor library
Project description
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()
