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.

Connect to the Cloud industrial devices
connect to cloud industrial devices

Waspmote can be configured to read the information coming from the bus and send it via wireless directly to the Cloud using WiFi, GPRS, GPRS+GPS, 3G or 4G radio interfaces.

Models and applications

Plug & Sense! Industry 4.0

Plug & Sense! Industry 4.0, can operate in three types of situations. It can be used to connect any sensor to an existing industrial bus; it can also add wireless connectivity to wired buses or even connect industrial devices to the cloud.

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.
