21.1. Introduction

Libelium offers communication modules for the most common wired communication protocols: RS-485, 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 these protocols.
Waspmote allows to perform 3 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 100 sensors currently integrated in the platform by
using specific sensor boards (e.g.: CO, CO , temperature, humidity, acceleration, pH, IR, luminosity, vibration, etc).
2
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 from the bus and send it to the Libelium IoT Gateway using
any of the wireless radio modules available: 802.15.4, ZigBee, DigiMesh, 868 MHz, 900 MHz, LoRa, WiFi, GPRS, 3G,
NB-IoT / Cat-M, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and RFID/NFC.
