MuMo - LoRa Gateway
Introduction: MuMo - LoRa Gateway
### UPDATE 10-03-2021 // the latest information / updates will be available on the github page:
https://github.com/MoMu-Antwerp/MuMo
What is MuMo?
MuMo is a collaboration between product development (a department of the University of Antwerp) under the name of Antwerp Design Factory and the Antwerp Fashion Museum.
The goal of the project is to build an open source IOT monitor system based on a LoRa network.
* It should be easy to set up.
* It should be easy to assemble.
* It must be scalable in terms of application area.
What the project MuMo contains:
MuMo Node
The MuMo Node is a low power device on AA batteries that can measure and transmit environmental parameters over a LoRa network. The parameters are temperature, humidity, ambient pressure and brightness.
*** The MuMo node can be extended with other functionalities to be used in other applications.***
MuMo Gatway
The MuMo Gateway is an active LoRa gateway that can receive and forward LoRa signals from the Node device over the internet. In this project the gateway will also be equipped with the same sensors of the MuMo Node device, air dust sensor and an bug trap that can be remotely monitored with a camera.
*** The gateway does not need to be equipped with sensors or a camera. It can also only serve to provide a LoRa network (non measuring gateway).***
MuMo Dashboard
The MuMo Dashboard is provided to create an overview web application of the network that is being created. It is made user-friendly with different functionalities. The dashboard can be fully customized to the wishes and application of the user.

Step 3: #Software - Prepare SD Card Raspberry Pi
Parts:
* Raspberry Pi
* Micro SD card.
Instructions:
1. 152
Make sure the SD card is flashed and that the right raspberry operation system (Raspberry Pi OS(32-bit) with desktop) image is installed on to the micro SD card. Follow the link below to find the right instructions to flash and prepare your micro SD card.
2. Insert your micro SD card into the Raspberry Pi.

Step 4: #Hardware - Prepare the Air Dust Sensor (optional)
Parts:
* seeed air dust sensor
* 2 x resistor (3.3 KΩ)
* Grove hat board
* 2 x shrink sleeves
Instructions:
1. Cut the red wire up to the connector.
2. Cut the yellow wire at a distance of 3 cm from the connector.
3. Cut the black wire at a distance of 2 cm from the connector.
4. Strip the end of each wire.
5. Put a small shrink sleeve over the yellow cable.
6. Put a large shrink sleeve over the yellow and black cable.
7. Solder the two resistors in series with the yellow cable of the connector in between.
8. Solder the other yellow cable on the side of the sensor to one of the resistors.
