# Connect the Grove PIR Motion Sensor to digital port D8

# SIG,NC,VCC,GND

pir_sensor = 8

grovepi.pinMode(pir_sensor,"INPUT")

while True:

try:

# Sense motion, usually human, within the target range

if grovepi.digitalRead(pir_sensor):

print 'Motion Detected'

else:

print '-'

# if your hold time is less than this, you might not see as many detections

time.sleep(.2)

except IOError:

print "Error"
