def getInfo(Number) : Getting hardware information of device board
Number : connector number of baseboard

def power(milModClass, OnOff) :Power ON/OFF the IR LED.
milModClass : module instance
OnOff : LED power ON(1) and OFF(0). This device need worm up time, it is about 0.5 sec. If you want to use this sensor continually, use holdConnect(milModClass) and holdDisconnect(milModClass), please.

def read() :Reading sensing data
return : Reflecting data

Example:
Proximity.holdConnect(mod0)
Proximity.power(mod0,1)#power ON
time.sleep(0.5)#worm up
Proximity.holdDisconnect(mod0)

...

Proximity.holdConnect(mod0)
readData = Proximity.read(mod0)
print "read data = ",readData
Proximity.holdDisconnect(mod0)
