• Wireless sensor networks

  A Wireless Sensor Network (WSN) is a board system with the connectivity  capability to sense data and/or to perform actions. 

• WSN mote

Sometimes the WSN  board is called a WSN mote.
The main objective of implementing a WSN mote is to capture physical objects in digital form and then transfer them to a certain server.
In general, a WSN mote consists of a microcontroller (MCU), sensor/actuator, and wireless module.
The MCU can be replaced by an MPU (microprocessor), depending on whether there is a battery issue or not.
A sensor can capture physical objects, such as temperature, humidity, and compass direction. 
An actuator can perform a certain action, such as lighting an LED, generating sound, or running a motor. 
The wireless module is used to transfer data from the mote to a network device like gateway, server or cloud application.
