This is a thermopile sensor for contact-less measurement of temperature.
There is a sample code for usage with pymlab Python library and USBI2C01A module:
from pymlab import config
#### Sensor Configuration ###########################################
cfg = config.Config(
i2c = {
"port": 0, # I2C bus number
},
bus = [
{
"type": "i2chub",
"address": 0x73,
"children": [
{"name": "thermopile", "type": "thermopile01", "channel": 4, },
],
},
],
)
cfg.initialize()
sensor = cfg.get_device("thermopile")
#### Measurement ####################################################
while True:
print "Ta ", sensor.getTambient(), " To ", sensor.getTobject1()
