Things in IoT-Ignite
What can I connect to IoT-Ignite?
Almost anything that has an internet connection can be connected to IoT-Ignite. It is also possible to connect anything that does not have a direct Internet connection through a gateway. Protocol between a “thing” and gateway may be Bluetooth, Zigbee or even your proprietary communication protocol. Check Devices and Things document for further information.
What is a Thing?
A thing is a sensor, actuator, or a node.
What is a Sensor?
It is a device which detects or measures a physical property and records, indicates, or otherwise responds to it.
In IoT-Ignite, a sensor is a physical or virtual component that can emit data.
What is an Actuator?
An actuator is a component of a machine that is responsible for moving/controlling a mechanism or system. They are devices that transform an input signal (mainly an electrical signal) into some form of motion.
In IoT-Ignite, an actuator is a physical or virtual component that can receive commands.
What is a Node?
A node is the simplest computing unit where related sensors and actuators are attached. Node collects data from sensors and may act on actuators. It may be a physical device like Arduino or NodeMCU or a virtual device in the form of an application.
IoT-Ignite provides a communication and thing definition protocol applicable between IoT-Ignite agent and node software.
What are Built-in Sensors or Actuators?
You can access sensors available on the device and acquire raw sensor data by using IoT-Ignite agent. This agent automatically detects sensors and actuators in your gateway and registers them to your IoT-Ignite service. It is possible to use sensors and actuators without writing a single line of code.
What are Built-in Processors?
Built-in processors combine device sensors’ data for a specific purpose like geo-fence, fall detection. For example, our processor example in IoT-Ignite agent uses acceleration, gravity sensor and gyroscope sensor to detect if a fall has occurred. This processor acts as a fall sensor.
