Industry 4.0

IoT Solutions

Industry 4.0

The main challenge of every business regarding Industry 4.0 is the collection of quality data, providing intelligence and reliability to the manufacturing processes and nurturing the KPI’s of each decisión level. This applies not only to industrial & food manufacturing but also to logistics.

The direct connection to the productive processes using the Industrial Internet of Things (IIoT) and also to the devices and control tools is the cornerstone of the Digital Transformation of the modern industry.

Industry 4.0

The challenge of modern industry

Modern Industry’s main challenge is to improve its competitiveness, optimizing the production processes with efficient and scalable solutions that allow the improvement of the operational efficiency and compliance with the norm.

There are a few common points subjected to improvement: 

  • Continuous improvement techniques such as Lean Manufacturing, Six Sigma, TPM and such, require the data to be trustworthy and in real-time in order to be implemented.
  • Managing the in-process product traceability is one of the main requirements.
  • Obtaining the overall equipment effectiveness (OEE) by direct connection to the devices is still uncommon.
  • The use of paper is still present, and also the manual introduction of data even if using screens.
  • Predictive maintenance techniques are still applied at a minimum, caused mainly by the lack of exact data collection from productive assets.
  • The production and waiting times of the in-process product is still, in a lot of cases, not known with precision.

The main challenge of the industry is to improve its competitiveness by reducing costs, optimizing production processes while respecting compliance.

Industry 4.0 Products


The set of Industrial Protocol modules for Waspmote allows the user to interface with different industrial buses:

Waspmote allows to perform three main applications:

Connect any sensor to industrial bus

diagram connect any sensor to industrial bus

Waspmote can be configured to work as a node in the network, inserting sensor data into the industrial bus already present.

Waspmote can obtain information from more than 70 sensors currently integrated in the platform by using specific sensor boards (e.g: CO, CO2, temperature, humidity, acceleration, pH, IR, luminosity, vibration, etc).

This way, the sensor information can be read from any industrial device connected to the bus.

Add wireless connectivity to wired buses

Add wireless connectivity to wired buses with Libelium Industry 4.0

Waspmote can be configured to read the information from the bus and send it to the Libelium IoT Gateway using any of the wireless radio modules available: 802.15.4, 868 MHz, 900 MHz, WiFi, 4G, Sigfox and LoRaWAN.

WasteWater Quality

Smart Water Xtreme for wastewater quality measurement in industrial environments.

All sensors/probes incorporate calibration inside. Very low power consumption. Sleep mode available. Robust sensor probes: PVC and stainless steel. 5-6 bar pressure resistance.

Optical and anti-fouling systems require less maintenance.
Fouling effect occurs when there is organic materials in the water. It creates a “bio-film” which adheres to the probes and provokes wrong measurements → quality decreases

A variety of mounting accessories for each sensor are available to the customer, to be placed in pipes or tanks. Protective wildlife accessories are also available.
