General
1. General
1.1. General and safety information
•In this section, the term “Waspmote”encompasses both the Waspmote device itself and its modules and sensor boards.
•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.
•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 specications 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 specied range of temperatures in the specications 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 using a car lighter as a power supply, be sure to respect the voltage and current data specied in the “Power Supplies”
section.
•If using a battery in combination or not with a solar panel as a power supply, be sure to use the voltage and current data
specied in the “Power supplies” section.
•If a software or 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.
•Waspmote is a device to be integrated in a casing so that it is protected from environmental conditions such as light, dust,
humidity or sudden changes in temperature. The board supplied “as is” is not recommended for a nal installation as the
electronic components are open to the air and may be damaged.
1.2. 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 specications and the environment described in the “Electrical Data”
section of this manual.
•Waspmote and its components and modules are supplied as electronic boards to be integrated within a nal product. This
product must contain an enclosure to protect it from dust, humidity and other environmental interactions. In the event of
outside use, this enclosure must be rated at least IP-65.
•Do not place Waspmote in contact with metallic surfaces; they could cause short-circuits which will permanently damage it.

Waspmote Plug & Sense!
2. Waspmote Plug & Sense!
The new Waspmote Plug & Sense! line allows you to easily deploy wireless sensor networks in an easy and scalable way ensuring
minimum maintenance costs. The new platform consists of a robust waterproof enclosure with specic external sockets to
connect the sensors, the solar panel, the antenna and even the USB cable in order to reprogram the node. It has been specially
designed to be scalable, easy to deploy and maintain.
Note: For a complete reference guide download the “Waspmote Plug & Sense! Technical Guide” in the Development section of
the Libelium website.
2.1. Features
•Robust waterproof IP65 enclosure
•Add or change a sensor probe in seconds
•Solar powered with internal and external panel options
•Radios available: Zigbee, 802.15.4, Wi, 868MHz, 900MHz and 3G/GPRS
•Over the air programming (OTAP) of multiple nodes at once
•Special holders and brackets ready for installation in street lights and building fronts
•Graphical and intuitive programming interface
2.2. Sensor Probes
Sensor probes can be easily attached by just screwing them into the bottom sockets. This allows you to add new sensing

2.6. Program in minutes
In order to program the nodes an intuitive graphic interface has been developed. Developers just need to ll a web form in
order to obtain the complete source code for the sensor nodes. This means the complete program for an specic application
can be generated just in minutes. Check the Code Generator to see how easy it is at:
http://www.libelium.com/development/plug_&_sense/sdk_and_applications/code_generator
Figure 7: Code Generator
2.7. Data to the Cloud
The Sensor data gathered by the Waspmote Plug & Sense! nodes is sent to the Cloud by Meshlium, the Gateway router specially
designed to connect Waspmote sensor networks to the Internet via Ethernet, Wi and 3G interfaces.
Thanks to Meshlium’s new feature, the Sensor Parser, now it is easier to receive any frame, parse it and store the data into a local
or external Data Base.

2.10. Models
There are some dened congurations of Waspmote Plug & Sense! depending on which sensors are going to be used. Waspmote
Plug & Sense! congurations allow to connect up to six sensor probes at the same time.
Each model takes a dierent conditioning circuit to enable the sensor integration. For this reason each model allows to connect
just its specic sensors.
This section describes each model conguration in detail, showing the sensors which can be used in each case and how to
connect them to Waspmote. In many cases, the sensor sockets accept the connection of more than one sensor probe. See the
compatibility table for each model conguration to choose the best probe combination for the application.
It is very important to remark that each socket is designed only for one specic sensor, so they are not interchangeable.
Always be sure you connected probes in the right socket, otherwise they can be damaged.

4.1.1. Specications
Maximum primary current: 100A
Turns ratio: 1:2000 approximately
Minimum resolution: 130mA approximately
Measurement range: 500mA ~ 40A
4.1.2. Measurement Process
The current clamp is a low cost sensor that outputs a current proportional to the current in the primary circuit. That current
(related with the primary current through a 1:2000 ratio) is converted into voltage through a load resistor obtaining a signal
readable by the mote’s analog-to-digital converter. The functions implemented to read the output value of the clamp, expressed
in RMS current amperes, are described in section“API”.
Below, a small sample of a code for reading the sensor is shown:
{
SensorSmartv20.ON();
SensorSmartv20.setSensorMode(SENS_ON, SENS_SMART_CURRENT);
delay(50);
oatvalue_current;
value_current=SensorSmartv20.readValue(SENS_SMART_CURRENT);

4.2.2. Measurement Process
The load cells used in the Smart Metering 2.0 Board, included in the PRO version of the board, are single point cells with a
Wheatstone bridge output in a full bridge conguration that requires connection to power supply, ground, positive output and
negative output (red, black green and white wires respectively). The result is a dierential voltage that is amplied and ltered
to get an analog voltage proportional to the weight on the cell. In gure 23 the output voltage of the cell related to the load on
it has been represented for three dierent models powered at 10V.
A sample code for reading the load cells is shown below:
{
SensorSmartv20.ON();
SensorSmartv20.setSensorMode(SENS_ON, SENS_SMART_LCELLS);
delay(50);
oatvalue_lcell;
