Introduction
1. Introduction
The new version of Waspmote Plug & Sense! Smart Parking, the solution for Smart Cities that allows citizens to detect
available parking spots.
The new device is easier and cheaper to deploy as it is mounted on the road surface. Unlike most market versions, it does not
need to dig a hole in the ground for installation, reducing installation time from 30 to 5 minutes and allowing to be replaced by
another unit in case of maintenance in just 10 minutes.
The smaller size -reduced over 50%-, its higher accuracy and reliability, and the faster time of detection, besides the independence
from temperature are also important features of new Smart Parking device.
New sensor system is fully compatible with LPWAN radio technologies -LoRaWAN and Sigfox- to enable long range and low
power consumption. It can be connected with both radios for the European 868 MHz band and for the 900-930 MHz band (US
/ Canada). One unique feature of the system is that it allows to use both radio technologies at the same time or changing from
one to the other using the manager system from the Cloud.
With the new sensor system, one base station can give service to thousands of devices around a range of several kilometers
in urban environment. This fact provides lower costs of installation since the number of base stations can be dramatically
reduced. Besides, the new sensor model has been optimized for really low-power operation, so the battery lifetime is extended
up to 10 years easily.
The new Smart Parking node has been granted with the CE / FCC / IC marks and provides a robust software which works
out-of-the-box. Developers do not have to cope with programming the nodes, they just have to specify the values of key
parameters in the rmware such as working cycle or night mode to be ready to work. Remote management and bidirectional
communication allows to change several parameters of the nodes from the Cloud. This means we can reprogram thousands of
nodes by just setting the right values from our web browser in the management platform.

General
2. General
2.1. General and safety information
• In this section, the term “Waspmote” encompasses both the Waspmote device itself and it enclosure.
• Read through the document “General Conditions of Libelium Sale and Use”.
• Do not allow contact of metallic objects with the electronic part to avoid injuries and burns.
• NEVER submerge the device in any liquid with the enclosure open.
• Keep the device in a dry place and away from any liquid which may spill.
• Waspmote consists of highly sensitive electronics which is accessible to the exterior, handle with great care and avoid
bangs or hard brushing against surfaces.
• Check the product specications section for the maximum allowed power voltage and amperage range and consequently
always use a current transformer and a battery which works within that range. Libelium is only responsible for the correct
operation of the device with the batteries, power supplies and chargers which it supplies.
• Keep the device within the specied range of temperatures in the specications section.
• Do not connect or power the device with damaged cables or batteries.
• Place the device in a place only accessible to maintenance personnel (a restricted area).
• Keep children away from the device in all circumstances.
• If there is an electrical failure, disconnect the main switch immediately and disconnect that battery or any other power
supply that is being used.
• If a hardware failure occurs, consult the Libelium Web Development section.
• Check that the frequency and power of the communication radio modules together with the integrated antennas are
allowed in the area where you want to use the device.
2.2. Conditions of use
• Read the “General and Safety Information” section carefully and keep the manual for future consultation.
• Use Waspmote in accordance with the electrical specications and the environment described in the “Hardware”section of
this manual.
• Do not place Waspmote in contact with metallic surfaces; they could cause short-circuits which will permanently damage it.
• IMPORTANT It is the responsibility of the installer to nd out about restrictions of use for frequency bands in each country
and act in accordance with the given regulations. Libelium Comunicaciones Distribuidas S.L does not list the entire set of
standards that must be met for each country.

How the node works
4. How the node works
Figure : Basic working loop diagram
As the diagram indicate, the basic loop of the node consists in read the sensor and send a frame when the parking slot change
it status. Then, it sleeps a desired time and starts the loop again.
Some events can forced the node to send a frame to the cloud. If a desired time elapsed since the last radio transmission, the
node will send a Keep-Alive frame. This frame only contains basic data from the node (parking slot status and battery status). It
is useful to know that there is no changes in the slot, but the node still working. The node also will send a frame each 24 hours
with the working data of the day (number of measurements, number of transmissions,…).

Sleep modes
5. Sleep modes
Plug & Sense! Smart Parking has 2 sleep modes: day mode and night mode. The second one has been developed to use when
the parking slot is expected to have fewer changes (i.e. at night). Each mode has its own conguration parameters. The gure
below shows an example for the node transmissions in a day. The time zone between 6 AM and 12 AM (in light gray) indicates
that the node are working in day mode. In this mode, the sampling of the parking slot is made more regular (1 minute) and the
Keep-Alive is only 2 hours. In the dark gray zone, from 12 AM to 6 AM, the node is working in night mode. As is shown in the
example, the sampling time is greater (10 minutes) and the Keep-Alive increases too (3 hours).
Example conguration:
Parameter Conguration
Sleep time 1 minute
Keep-Alive 2 hours
Night Mode start hour 00 hours
Night Mode duration 6 hours
Night Mode Sleep Time 10 minutes
Night Mode Keep-Alive 3 hours
Figure : Example conguration
Figure : Day and night modes example
5.1. Day mode
It is the basic working mode and it has 2 congurable parameters:
• Sleep time: Sleep time between consecutive sensor measurements. 2 minutes option is congured by default.
• Keep-Alive: Elapsed time since last transmission to trigger a Keep-Alive frame. 10 hours option is congured by default.
This frame only contains basic data from the node (parking slot status and battery status). It is useful to know that there
are no changes in the slot, but the node still working. This mode can be disabled using both the USB Programmer or the
Remote Manager.

Sleep modes
5.2. Night mode
This mode has been developed to use when the parking slot is expected to have fewer changes (i.e. at night) and it has 4
congurable parameters:
• Night Mode start hour: Beginning hour of the night mode. 22 hours option is congured by default.
• Night Mode duration: Night mode duration time. 8 hour option is congured by default.
• Night Mode Sleep Time: Sleep time between consecutive sensor measurements (during night mode). 10 minutes option
is congured by default.
• Night Mode Keep-Alive: Elapsed time since last transmission to trigger a Keep-Alive frame (during night mode). 4 hours
option is congured by default. This frame only contains basic data from the node (parking slot status and battery status).
It is useful to know that there is no change in the slot, but the node is still working.
This mode can be disabled using both the USB Programmer or the Remote Manager.

Transmission modes
6. Transmission modes
Plug & Sense! Smart Parking has 5 transmission modes allowing to the user to choose between Sigfox, LoRaWAN y their
combinations:
• Sigfox. This mode only use the Sigfox radio to send the data collected by the node. This mode is selected by default.
• LoRaWAN. This mode only use the LoRaWAN radio to send the data collected by the node
• Sigfox + LoRaWAN. In this mode the data collected is sent using the 2 radios. It is recommended to test the node with the
two transmission technologies.
• Sigfox →LoRaWAN. This mode uses Sigfox radio as primary radio. If there is an issue with the Sigfox radio, it will use
LoRaWAN to send the frames.
• LoRaWAN →Sigfox. This mode uses LoRaWAN radio as primary radio. If there is an issue with the LoRaWAN radio, it will
use Sigfox to send the frames.
