Mounting and Positioning the Sensor Node
•
Position the sensor node towards the sun, making sure the solar panel is oriented so that it receives optimal sunlight throughout each
season. It may be necessary to periodically adjust the sensor node position as the path of the sunlight changes throughout the year or
if tree and leaf growth alters the amount of sunlight reaching the solar panel.
•
Make sure the sensor node is mounted a minimum of 1.8 m (6 feet) from the ground or vegetation to help maximize distance and
signal strength.
•
Consider using plastic poles such as PVC to mount the sensor node as certain types of metal could decrease the signal strength.
•
Place the sensor node so there is full line of sight with the next sensor node. Use a repeater if there is an obstruction between sensor
nodes.
•
There should not be more than five sensor nodes in any direction from a repeater or the manager. Data from sensor nodes travels or
“hops” across the network and may not reach the station if the sensor node is more than five hops away.
Input Connections
The pulse input sensor has two input connections. The white wire (+) is powered at 3.3 V through a 100 K
Ω
resistor. This power is
supplied from the sensor node battery. The black wire (-) is connected to the sensor node’s ground connection. The input cable can be
connected directly to screw terminals on the sensor or to sensor cables with the included wire nuts.

Connection Using Wire Nuts
Important:
If using wire nuts, make sure the connection is protected from the elements.
1.
Strip 1 cm (0.39 in.) of insulation from the end of wires, taking care not to nick the metal conductors.
2.
Twist the stripped wires together clockwise and then screw on the wire nut clockwise.
3.
Check the connection by gently pulling on the wires to verify a solid mechanical connection. Always strain-relief the connection to
make sure that the connection is not broken by being jerked or repeatedly worked back and forth.
Pulse Input Sensor Mounting Guidelines
•
Coil and secure excess cable with cable ties.
•
If cable is on the ground, use a conduit to protect against such things as animals, lawn mowers, and exposure to chemicals.
•
When making a connection to a third-party sensor, take time to make sure that the connection is reliable and protected from rain,
dirt, and direct exposure to the elements. Refer to the manufacturer’s product documentation for additional information on
system configuration.
