Python-SL19

The SL19 xChip is equipped to measure temperature as a function of infrared light/radiation (IR) radiating from objects in its field of view. Is is based on the MLX90614 in which a IR sensitive thermopile detector chip and signal conditioning ASIC are integrated.

The MLX90614 is factory calibrated in wide temperature ranges: -40-125˚C for the ambient temperature and -70-380˚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.

Example

from xCore import xCore
from xSL19 import xSL19

# SL19 instance
SL19 = xSL19()

# configure SL19
SL19.init()

while True:
    tempAmbient = SL19.getAmbientTempC()	# returns ambient temp in degree celcius
    tempObject = SL19.getObjectTempC()		# returns object temp in degree celcius

    # prints on console
    print('Ambient: ',tempAmbient,' C')
    print('Object : ',tempObject,' C')
