SiteVisor Sensors

This repository contains code for sensors used in the SiteVisor Project.

Sensors list

Simulated environmental sensor

This code randomly generates simple data within the specified range and sends it to a Kafka Broker accesible over HTTP via Kafka Bridge.

Setup dependencies:

pip install -r requirements.txt

Example usage:

python .\simulated_env_sensor.py --topic='my-topic' --sensor-id='sensor-42' --min-value=10.0 --max-value=30.0 --sensor-type='temperature' --unit='C'

To run mutliple simulated sensors at once:

python run_multiple_sim_sensors.py --num-sensors=5 --topic='my-topic' --base-min-value=15.0 --base-max-value=25.0 --sensor-type='temperature' --unit='C'

DHT11 Sensor with Raspberry Pi 4B

Script to read data from DHT11 sensor on GPIO04 and send it to Kafka Bridge.

Setup

Recommended to setup a new venv. Then install dependencies:

pip install -r requirements_rpi.txt

Example usage:

python sitevisor_dht11_sensor.py --topic='my-topic' --sensor-id='dht11' --ip='sitevisor.local'
