Connected sensors and data visualization to measure hardness at work

Conference


Hardness at work is defined by marked physical constraints, an aggressive environment and the rhythms of work.

We decided to make objective measurements of these factors via different types of sensors (accelerometer, gyroscope, temperature, ...) in order to obtain an image of the gestures and the environment of the worker by means of a data vizualisation tools.

We will begin by presenting the selected sensors then technologies (Arduino, MQTT, Node-Red) implemented for the collection of data on the environment but also on the positioning of the worker.

In a second part, we will discuss the exploitation of these measures using a TimeSeries InfluxDB database and Dashboard Grafana to visualize and analyze the physical conditions of work as well as the type and repetitiveness of gestures related to this work.
