Mounting and Positioning the Mote 
• Close the mote and use a padlock to keep it secure. Mount the mote vertically using cable ties or screws. 
• Make sure the mote is mounted a minimum of 1.8 m (6 feet) from the ground to help maximize distance and signal strength. 
• Consider using plastic poles such as PVC to mount the mote as certain types of metal could decrease the signal strength. 
• Place the mote so there is full line of sight with the next mote. Use a repeater if there is an obstruction between motes. 
• There should not be more than five motes in any direction from a repeater or the manager. Data from sensor motes travels or “hops” 
across the network and may not reach the station if the mote is more than five hops away. 
• Mount the sensor so that at least 10 cm (4 in.) of the sensor cable is placed in the medium that is being measured. The temperature  
sensor is approximately 0.32 cm (0.126 in.) from the end of the stainless steel tip.
