19.1. Introduction
Libelium created communication modules for the most common wired communication protocols: RS-485, RS-232, CAN Bus and
Modbus. These are widely used standards in the industrial and automation market for connecting devices and sensors, not in a
wireless way but with cables. The user can interface Waspmote ecosystem with this protocols.
Waspmote allows to perform three main applications:
1º- Connect any sensor to an existing 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, CO
2
, temperature, humidity, acceleration, pH, IR, luminosity, vibration, etc). This way, the sensor information can
be read from any industrial device connected to the bus.

2º- Add wireless connectivity to wired buses
Waspmote can be configured to read the information coming from the bus and send it wirelessly using any of the wireless
modules available in the platform to a base station or to another node connected to another bus. The available wireless
technologies are: WiFi, 3G, GPRS, 802.15.4, ZigBee, Bluetooth, Bluetooth Low Energy, RF-868MHz, RF-900MHz, LoRaWAN, LoRa,
and Sigfox.

3º- Connect to the Cloud industrial devices
Waspmote can be configured to read the information coming from the bus and send it wirelessly directly to the Cloud using
WiFi, 3G and GPRS radio interfaces.
