iot-sim

Representational simulation of IoT devices.

About

This project creates simulated IoT devices and facilities. Realistic data is generated based on the type of device and time of day. IoT telemetry data can be handled by a custom user defined function.

Devices

• Energy Device
• Tank Device
• Wind Device

Device API

/**
 * Device

 * @param {String} connectionString  - connection parameter for Azure IoT hub.
 * @param {String} profile  - device signature.
 * @param {boolean} log  - True=print fancy output console/False=no output
 * @param {function} handler - User defined function to handle the telemetry data

Facility API

/**
 * Facility
 *
 * Models the composition of IoT objects into a single IoT "Facility"
 *
 * @constructor
 * @param {string} name  - name of the facility.
 * @param {array} devices  - IoT devices in the facility.
 * @param {array} geolocation  - lat and lon of the facility.
 * @param {number} frequency - milliseconds between messages.
