Home Automation System

Install home automation system, web server, and MQTT broker (MQTT server) on microcontroller boards such as Raspberry Pi and Orange Pi, and use them as a gateway, which acts as the hub of the home automation system. Place various sensor devices, LED lighting, actuators, and other peripheral devices on the same network as the gateway, and make them work together through the gateway. Additionally, you can equip the gateway with optional features such as SIP-VoIP telephony and surveillance cameras.



The gateway and the peripheral devices in the home network


With various rule settings, it becomes possible to immediately notify third parties of abnormalities by triggering email or phone calls based on the output from motion sensors or tilt sensors, for example. 

MQTT Protocol

Communication between the gateway and each device is performed using the MQTT protocol. This is a lightweight communication method that provides communication assurance and security through open-source technology. Mosquitto is adopted as the MQTT server.

The Devices and The System

Gateway

Home gateway

The gateway, which serves as the core of the system, monitors and controls various devices. In addition, it is equipped with a VoIP telephone system and a music player to also serve as a security system.

Home Gateway

Motion Sensor

motion sensor

It is a sensor device that incorporates radar motion sensors, tilt sensors, and other sensors. It plays an important role in building a security system.

Motion Sensor

Pulse Oximeter

health check

It is a device that measures oxygen saturation, pulse rate, and body temperature. The measurement data is automatically sent to the gateway and treated as a trigger for other function activations.
