This project gives a simple way to deploy temperature and humidity sensors around your house using cheap components and the MQTT protocol.

Original Project - corbanmailloux

The sensor publishes to 2 MQTT topics:

• Temperature topic (example: home/room/temperature): The sensor publishes the temperature in Celsius (example: 25.10).
• Humidity topic (example: home/room/humidity): The sensor publishes the relative humidity in percent (example: 37.40).
