Check the product specifications 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! 2.10. Models There are some defined configurations of Waspmote Plug & Sense! depending on which sensors are going to be used. Waspmote Plug & Sense! configurations allow to connect up to six sensor probes at the same time. Each model takes a different conditioning circuit to enable the sensor integration.

Page 14: Hardware
Hardware 3. Hardware 3.1. General Description The sensors are active on the Events Sensor Board 2.0 while Waspmote is in Sleep or Deep Sleep mode. When a sensor picks up a value higher than a previously programmed threshold, a signal is generated which wakes the mote from its low consumption status and tells it which sensor has generated the signal.

Page 18: Measurement Process
Sensors 4.3.2. Measurement Process The PZ-01 and PZ-08 sensors are two piezoelectric laminates which generate voltage at its output when subjected to a distortion. This therefore makes it useful as a system to measure vibrations caused by acceleration, knocks or contact, being especially useful in low consumption applications as they do not need power voltage for their operation.

Sensors 4.5.2. Measurement Process There are three liquid level sensors whose operation is based on the status of a switch which can be opened and closed (depending on its placing in the container) as the level of liquid moves the float at its end. The main differences between the three sensors, regarding its use in Waspmote, are to be found in their process for placing them in the container (horizontal in the case of the PTFA3415 and PTFA0100 sensors, vertical for the PTFA1103 sensor) and in the material they are made of (the PTFA1103 and PTFA3415 sensors recommended for edible liquids and certain acids and the PTFA0100 for heavy oils and...

Board configuration and programming 5. Board configuration and programming 5.1. Hardware configuration The different sensors must be connected on the connector’s pin strips. The pin function is printed on the board: power supply (+3.3V), circuit’s ground (GND) or connector’s output signal (Vout). Although the output of many of the sensors can be connected indiscriminately to the input pins, for both resistive and switch sensors, the user must maintain precaution to avoid short- circuits and erroneous connections which may damage both the sensor and board, following the instructions in this manual and the sensor’s data sheet, and consulting the distributor with any queries.

Page 42: Consumption
Consumption 7. Consumption 7.1. Power control The power of the Events Sensor Board 2.0 is drawn from the Waspmote 3.3V line and is controlled by the solid state switch which is accessed through the 2x11 connector, defined as SENS_3V3_PW in the application. From this switch it is therefore possible to completely activate or deactivate the Events Sensor Board 2.0 power (see Waspmote manual for more details about the switches to manage the mote’s power and the appropriate section in the WaspmotePWR API manual’s library for more information on its handling).
Page 43: Low Consumption Mode
Care of new sensors • Libelium has chosen a series of sensors which are outstanding thanks to their high functionality and low consumption in active mode. Make sure that the sensors that are installed in this board maintain minimum consumption in this status, since they are thought to be always operating and wake Waspmote when any event occurs.
