Mycélium 2.0

Welcome to Mycelium 2.0

Rennes' new metro line B greatly facilitates travel for its citizens. In order to compensate for the environmental impacts of the construction of this line, the city of Rennes has committed to renaturalizing certain green spaces. The Mycelium 2.0 project focuses on the renaturation of the Green Cross, located on the Beaulieu campus, in front of the INSA.

To carry out an environmental monitoring of the Green Cross, the Mycelium 1.0 project deployed a monitoring system of a network of intelligent and low energy sensors on the site. The aim of Mycelium 2.0 is to improve the existing system and to extend it by taking into account the various existing constraints. A low consumption is necessary for the system to remain independent, ecological and long-lasting. Mycelium 2.0 uses a larger number of sensors as well as a device including a camera in order to reinforce the data collected on the Green Cross, in an automated way, by capturing extreme but also daily events.

The Green Cross

Currently under renaturation, this green space offers a place for nature in the heart of the Beaulieu campus. The main objective of this area is to bring up groundwater to three surface water points. Thus, the study of these water points is essential.

A multidisciplinary team

In collaboration with the Geosciences Rennes laboratory and following its request, Mycelium 2.0 aims to equip the Green Cross area with sensors, in order to obtain statistics on the response of the environment to climate change and forcing.

The Mycelium 2.0 team is therefore multidisciplinary, since it includes engineers from the Rennes Geoscience Institute, as well as a teacher-researcher and engineering students from INSA Rennes.

The Mycelium 2.0 project includes among its new sensors a camera enabling the visual monitoring of biodiversity by motion detection. To this end, it is an extension of the FoxyFind Internet of Things project, which was carried out in parallel by students of the INSA Rennes computer science department.

Partners

Laurent LONGUEVERGNE
Julien MOREAU

Scientists from the OSUR, and particularly from the Geosciences Rennes laboratory, are both clients and external partners of Mycelium 2.0.

TERRA FORMA

Mycelium is part of the national environmental monitoring project TERRA FORMA, coordinated by Laurent LONGUEVERGNE, within the CNRS. It allows to monitor the soil and water capital, as well as to collect data related to biodiversity and chemical and entropic pressure generated by human beings on a national scale.

Equipment

A variety of materials were used in the project:

1. All
2. Mycelium
3. FoxyFind

ConnecSenS box

Box with several sensors (temperature, humidity, acceleration according to x,y and z) taking measures and sending them to the gateway.

LoRaWAN Gateway

Gateway to connect the sensors to the cluster.

Raspberry Pi cluster

Cluster used to do all the processing associated with the project scenarios.

Raspberry Pi and camera

Used to capture the Green Cross wildlife and send photos to the cluster.

Rain gauge

Allows to measure the rainfall of the site and to send the data to the cluster.

VPS

VPS to perform calculations instead of the cluster in case of cluster overload.

Scenarios

FOXYFIND

The purpose of the FoxyFind scenario is to study the wildlife of the Green Cross. When an animal passes in front of the camera, the latter detects its movement and sends a picture to the cluster. The cluster uses a pre-trained animal recognition model to name the animal in the picture, then sends a Discord message containing the name of the animal and the picture that was taken. The idea at the genesis of this project is to detect a rumored fox in the area, but this extends to other species.

Example of a message received upon detection of a fox.

SEASONAL NORMALS

The Seasonal Normals scenario is intended to alert the user if the day's temperature measurements captured by the SoLo node fall outside the normal range of expected temperatures for the current month. This scenario is useful to account for ongoing climate change, with an increase in observed lags from the seasonal normals observed.

THUNDERSTORM

The purpose of the Thunderstorm scenario is to account for thunderstorm events that can occur in the area. These events are particularly interesting because they are often accompanied by multiple phenomena, some more violent than others: intense rain, wind gusts, high atmospheric pressure, heat... These phenomena can have a very strong impact on the fauna and flora of the Green Cross. It is therefore essential to alert the user when a stormy episode is observed. This scenario requires many sensors, such as the SoLo node, the multi-parameter sensor, or the flow meter.

Features

Main features of Mycelium 2.0

Automatisation icônes créées par Becris - Flaticon

Automation

The intelligent node can react to certain abnormal situations and the system will also send automatic notifications to administrators.

Bateau icônes créées par monkik - Flaticon

Containerization

The system is based on the Kubernetes container orchestration platform, which provides portability and scalability.

Visualisation de données icônes créées par Freepik

Visualization

With Grafana and InfluxDB, data can be visualized universally, quickly and efficiently.

Scalable icons created by Freepik - Flaticon

Scalability

The system can decide to shift part of the processing from the cluster to the VPS completely autonomously depending on the workload.
