Features

The project consists of 4 main files and should be executed on the Raspberry Pi.

• mam_publish.js: Publishes randomly generated numbers to the Tangle using MAM.
• mam_receive.js: Extract the stored data from the Tangle using MAM and display the data.
• sensor.js: The DHT11 sensor data (temperature and humidity) is read and displayed.
• mam_sensor.js: The DHT11 sensor data is read and published to the Tangle using MAM.

Installation

npm install
