    In a technological market where the demand for professional solutions is increasingly challenging, Libelium has decided to focus on the strategic shift to offer complete IoT technology solutions specialising in vertical applications.

    This decision marks the operational closure of the e-commerce Cooking Hacks, the business division where Libelium has offered electronic products for amateur audiences (makers, students...). This shutdown will be effective from December 20, 2019. Until that date, Cooking Hacks will offer very attractive prices with different campaigns of stock liquidation. Libelium will continue to offer technical support and all products purchased will maintain their current warranty period.

    "As a pioneer in IoT, Libelium has offered technology for all audiences since the beginning in 2006. It is time to specialize in products and solutions with higher added value, better quality, accuracy and reliability; features that require more developed platforms than Arduino and Raspberry Pi. This requires allocating all of the company's resources to larger projects, which excludes the retailing of lower-demand components," explains Alicia AsĂ­n, co-founder and CEO of Libelium.

    Moreover, Libelium will continue offering its Waspmote OEM business line with all its components and actual references published on the catalog. These products will continue being available to be ordered through the sales team channel.

    Cooking Hacks started in 2011 with the intention of extending electronic for makers to any audience in an educational, accessible and fun way. Over the last 8 years, the online store has offered a complete catalogue of products and components, documentation, tutorials and a forum for resolving technical issues. Not in vane, Cooking Hacks has reached almost 30,000 subscribers to the newsletter and more than 11,500 followers in social media. This audience is evolving towards the professional side of IoT through the corporate website Libelium and The IoT Marketplace, the online store that offers complete solutions that include hardware and software "ready to use".

  • E-Health application developed with MySignals first winner in health competition ISHIC 2017November 28, 2017

    The project “Smart m-Health Application for Pregnancy Care Using Body Area Networks” developed with MySignals Hardware platform won the Most Innovative Project award at the 2nd International Saudi Health Informatics Conference (ISHIC) 2017 in Riyadh, Saudi Arabia.

  • Reading Blood Oxygen Saturation (SpO2) and Pulse through MySignals / ArduinoNovember 28, 2017


    The MySignals HW BLE v2 – eHealth and Medical IoT Development Platform for Arduino contains sensors that measure more than 20 biometric parameters. One of the most interesting is the Bluetooth LE SpO2 sensor How to get started reading live data and visualizing it on the TFT display of the board?

    What is the MySignals HW Kit?

    The MySignals HW kit contains a shield that requires an Arduino Uno as base. In contrast to the (more expensive) MySignals SW kit, the HW kit is rather basic. Powering it up results in a white screen, instead of a nice interface on the screen. The rest is up to the software developer. As the development is based on Arduino, you need the latest version of the Arduino IDE.

    Health SDK

    The MySignals libraries are not available through the Arduino Library Manager repository, but need to be installed manually. The download link to the latest version is a bit hidden in the tutorial at step 5 – currently, the SDK is at version 2.0.1.

    Extract the zip file. This gives you two folders: libraries and examples. The libraries folder contains 5 different libs – you need to install all of these through the Arduino IDE: Sketch > Include Library > Add .ZIP Library…. Afterwards, restart the Arduino IDE to also see the examples in File > Examples.

    Bluetooth LE Pulse Oximeter

    To get started, I decided to test the Bluetooth LE SpO2 sensor first. The small measurement device requires two AAA batteries and clips to your fingertip. By pressing the single button on the device, the sensor activates for a certain time, advertises itself via Bluetooth LE and starts measuring pulse and SpO2 through a (red) light sensor.

    Unfortunately, the examples in the HW Kit SDK you just downloaded only include an example for the wired pulse oximeter, but not for the Bluetooth LE variant. The relevant example is available in the tutorial in section You need the TFT example.

    Be careful not to use the TFT BLE Example from the tutorial section 7.1.2, which also uses the SpO2 sensor – that version of the example misses a few lines of Bluetooth init code (to activate the UART Flow control) and fails to run. Only version 2.0 of the example works; version 0.1 in section 7.1.2 of the tutorial doesn’t.

    Copy the code to your Arduino IDE. It doesn’t work out of the box, though – you still need to configure the code.

    Pulse Oximeter Bluetooth MAC address

    Close to the top, the example code contains a line “Write here the MAC address of BLE device to find”.

    Unfortunately, the MAC address of the pulse oximeter isn’t printed on the device or listed anywhere on the kit. Therefore, you can use an app like BLE Scanner for Android:


    Once the app finds your SpO2 device (named Libelium), you can directly transcribe the MAC address – just remove the : separators. In my case, the corresponding Bluetooth MAC address to use in the Arduino code is:

    char MAC_SPO2[14] = "00A050172D27";

    Pulse and SpO2 Reading

    Now, compiling and uploading to the Arduino controller works. For some reason, the MySignals HW kit continuously outputs strange data over the serial port. However, as the tutorial example uses the TFT display for showing the measurements, we can ignore the serial output.


    After running the example, press the button on the pulse oximeter and wait several seconds until the board finds the BLE sensor, connects, subscribes and gets the real-time measurements.

    In case you want to directly use the sensor, e.g., from a custom mobile app: a bit more information about the BLE profiles is published in a short PDF. The GATT profile information isn’t provided by the manufacturer, according to a recent forum post.

  • Water efficiency and safety solution in living areas with Waspmote Sensor PlatformJune 13, 2017


    Water and electrical supply are two of the main concerns for public authorities and to improve its management helped by IoT can suppose important economic savings.

    Waspmote Sensor Platform can be used to develop Smart Water infrastructures as drainage or water supply plans, leakage detection services, network performance optimization and GIS management.

    Libelium has participated in iWesla, an European project which stands for improving water efficiency and safety, developing and deploying a demand-side cyber-physical system (CPS) to optimize the water consumption efficiency and safety in living areas.

    In this project, engineers installed Waspmote Sensor Platform to develop the wireless sensor networks. It is inside an encapsulation model in order to protect the board. As a gateway, they used a Meshlium Gateway provided by Libelium. Besides, the deployment also included high-accuracy water flow meters installed in the main water supply pipe of the living area to provide real-time water flow data and solenoid-based electric valves to control (open-close) the water supply into the living area.


    Waspmote Sensor Platform gathers data and send them through different communication protocols (GPRS, 3G, 4G, LoRaWAN, LoRa, Sigfox, 868 MHz, 900 MHz, ZigBee, 802.15.4, WiFi, RFID, NFC and Bluetooth 4.0) to the gateway. In this case, it uses 3G.

    Meshlium gateway sends the data to the cloud by means of an Ethernet connection in order to visualize the disaggregated water usage made by all consumption points in a Sofia2 based Application.


    The detection of abnormal water consumption is a key factor for facilities management. When this system detects deviations in normal data warns the users and enables them to actuate over the valves. This water efficiency and safety solution helps an early detection of potential damages caused by leaks or open taps and can mean savings up to 50% of the water consumption.
