Installation of Sphensor equipment
4.1
Guidelines for placement
The Sphensor line devices communicate with each other via radio. Before proceeding to their placement and
installation consider the following:
➢
Radio devices are subject to possible interference. Sphensor devices operate on the 2.4 Ghz fre-
quency, the same used by common equipment such as Wi-Fi networks on PCs, Bluetooth, cordless
phones, presence and alarm detection systems, video surveillance systems.
➢
The presence of special materials blocks the diffusion of the signal, absorbing or reflecting radio wa-
ves. Elements in metal, cement, plaster and bulletproof glass, for example, represent highly absor-
bing obstacles.
➢
The location of Sphensor devices that require the use of an external power supply is constrained by
the availability in the immediate vicinity of a socket.
➢
The location of Sphensor Gateway is constrained by the current socket and RJ45 socket for LAN con-
nection.
Install the Sphensor Gateway in a central location relative to the sensors, in sufficiently large rooms and free
of major barriers and obstacles. The antenna shall be positioned perpendicular to the plane of support of the
device.
Install the sensors in the most representative location of the area and environmental parameter to be moni-
tored. The models with battery operation offer a high flexibility of placement, not needing cables for power
supply.
Install Sphensor repeaters if the distance between sensors and Sphensor Gateway is excessive or in the pre-
sence of obstacles that are difficult to overcome by radio transmissions and, above all, to allow the Thread
communication network to operate with multiple communication paths; this increases the overall reliability
of the communication system.
If the area to be monitored is composed of several environments, where important obstacles are present, it
may be useful to subdivide the entire area into sub-areas (see
Errore. L'origine riferimento non è stata tro-
vata.
).
4.2
Installation
If the Sphensor sensor network has been subdivided into sub-areas, we recommend proceeding by sub-area.
➢
Place the Sphensor Gateway in the predetermined location. Connect the power and network cables.
Connect the antenna and place it perpendicularly to Sphensor Gateway. Turn on the device and check
the power of LED
USB pwr
and
On
.
➢
Place the remaining devices in the predetermined place by connecting them to the external power
supply, if the model allows it, and turn them on by pressing the switch accessible from the hole on
the upper hemisphere. Before any wall mounting, check the correct data transmission.
➢
Disconnections and signal instability are generally attributable to the sensors' excessive distance to
Sphensor Gateway or the presence of obstacles. In this case, use one or more Sphensor repeaters.
Also consider that low-power sensors need to refer, in their immediate vicinity (radio range), to a
