Introduction

A sensor can be any type of sensor ranging from a temperature measurer to an snmp device.

Here we will give a small overview of a couple of sensors and how these sensors are being configured through the XML. If you would like to use the Dashboard, then please refer to the following article Sensor Configuration from Scratch.

Furthermore, for a sensor to work, it needs a gateway device to function. If no gateway has been configured, please refer to the Devices page.

We do have a List of approved Sensors, where we will take the examples from.

A physical interface that connects to our system. Depending of its technology, it will be managed by a specific module (for example, a modbus device and a snmp sensor are configured in a different way). When we configure a device, we detail the way in which we connect to it (baud rate, IP, passwords, or whatever information is necessary to connect to it).

Example of a digital input (DI)

Here we have an example of an DI. This snippet has been taken from a configuration of an ADAM-4051, which has 16 DI's.
