Important:
All documents and any examples they contain are provided as-is and are subject to change without notice. Except
to the extent prohibited by law, Libelium makes no express or implied representation or warranty of any kind with
regard to the documents, and specically disclaims the implied warranties and conditions of merchantability and
tness for a particular purpose.
The information on Libelium’s websites has been included in good faith for general informational purposes only.
It should not be relied upon for any specic purpose and no representation or warranty is given as to its accuracy
or completeness.
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 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.

Waspmote Plug & Sense! - Sensors Guide
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 specications 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.

2. Introduction
In this document, all the possible congurations of the Plug & Sense! line are described, including a general
description of all the possible applications and the technical specications of the sensors associated to each one
of them.
For a deep description of the characteristics of the Plug & Sense! line, please refer to the Waspmote Plug & Sense!
Technical Guide. You can nd it, along with other useful information such as the Waspmote and Sensor boards
technical and programming guides, in the Development section of the Libelium website at http://www.libelium.com/
development/plug-sense
For detailed info about sensors or probes we do NOT recommend this Guide, but the dedicated guide for the
sensor board. Example: if you have a Plug & Sense! Smart Cities PRO, we advise reading the Smart Cities PRO
Technical Guide.
Note that no code for reading the sensors has been included in this guide. For programming the Waspmote Plug
& Sense! notes, please use the default examples provided for each sensor, available at: http://www.libelium.com/

Figure: Image of Waspmote Plug & Sense!
3.1. Internal sensors
3.1.1. Accelerometer
Waspmote has a built-in acceleration sensor LIS3331LDH, by STMicroelectronics, which informs the mote of
acceleration variations experienced on each one of the 3 axes (X,Y, Z).
The integration of this sensor allows the measurement of acceleration on the 3 axes (X, Y, Z), establishing 4 kinds
of events: Free Fall, inertial wake up, 6D movement and 6D position which are explained in the Interruption
Programming Guide.
Figure: Accelerometer
The LIS331DLH has dynamically user-selectable full scales of ±2g/±4g/±8g and it is capable of measuring
accelerations with output data rates from 0.5 Hz to 1 kHz.
The device features ultra low-power operational modes that allow advanced power saving and smart sleep to
wake-up functions.

-11- v7.7
Waspmote Plug & Sense! - Sensors Guide
The accelerometer has several power modes, the output data rate (ODR) will depend on the power mode selected.
The power modes and output data rates are shown in this table:
Power mode Output data rate (Hz)
Power down --
Normal mode 1000
Low-power 1 0.5
Low-power 2 1
Low-power 3 2
Low-power 4 5
Low-power 5 10
This accelerometer has an auto-test capability that allows the user to check the functioning of the sensor in the
nal application. Its operational temperature range is between -40 ºC and +85 ºC.
The accelerometer communicates with the microcontroller through the I2C interface. The pins that are used for
this task are the SCL pin and the SDA pin, as well as another interruption pin to generate the interruptions.
The accelerometer has 4 types of event which can generate an interrupt: free fall, inertial wake up, 6D movement
and 6D position.
These thresholds and times are set in the WaspACC.h le.
To show the ease of programming, an extract of code about how to get the accelerometer values is included
below:
{
ACC.ON();
ACC.getX();
ACC.getY();
ACC.getZ();
}
Some gures with possible uses of the accelerometer are shown below:

More information about interruptions generated by the accelerometer can be found in the chapter “Interruptions”
and in the Interruption Programming Guide.
Related API libraries: WaspACC.h, WaspACC.cpp
All information about their programming and operation can be found in the Accelerometer Programming Guide.
All the documentation is located in the Development section in the Libelium website.

3.2. Sensor probes
All sensing capabilities of Waspmote Plug & Sense! are provided by sensor probes. Each sensor probe contains one
sensor, some necessary protections against outdoor environmental conditions and a waterproof male connector.
The standard length of a sensor probe is about 150 mm, including waterproof connector, but it could vary due to
some sensors need special dimensions. Weight of a standard probe rounds 20 g, but there are some special cases
where this weight can rise.
Sensor probes are designed to be used in vertical position (with the sensor looking to the ground). In this position,
the protection cap of each sensor probe is eective against rain.

Calibrated gas sensors are manufactured once the order has been placed to ensure maximum durability of the
calibration feature. The manufacturing process and delivery may take from 4 to 6 weeks. The lifetime of calibrated
gas sensors is 6 months working at maximum accuracy. We strongly encourage our customers to buy extra gas
sensors to replace the original ones after that time to ensure maximum accuracy and performance.

This is a light-to-digital converter that transforms light intensity into a digital signal output. This device combines
one broadband photo-diode (visible plus infrared) and one infrared-responding photo-diode on a single CMOS
integrated circuit capable of providing a near-photopic response over an eective 20-bit dynamic range (16-bit
resolution). Two integrating ADCs convert the photo-diode currents to a digital output that represents the irradiance
measured on each channel. This digital output in lux is derived using an empirical formula to approximate the
human eye response.
