Since 1976, when Legionella was first discovered, it has become essential for building owners to take steps to prevent the spread of this bacterium, which thrives in water environments with temperatures between 35 and 40°C.
Monitoring the temperature of domestic hot water systems in buildings helps prevent the risk of Legionella growth.
Here's how to prevent the spread of Legionella using smart sensors.
The Role of IoT Sensors in Combating the Spread of Legionella
First and foremost, it is important to note that Legionella thrives in environments where water accumulates, regardless of its source. Artificial water systems, which are often installed in buildings, also promote its growth.
Since 2010, monitoring for Legionella in domestic hot water production, storage, and distribution systems has been mandatory in France. This applies primarily toPublic Access Building. It is therefore necessary to monitor the temperatures of domestic hot water (DHW) systems. IoT sensors eliminate the need for manual temperature readings. These sensors can transmit temperature data from DHW systems remotely.
IoT temperature monitoring solutions for Legionella surveillance
At Enless, we offer wireless sensors designed to measure temperatures in domestic hot water systems. These standalone sensors are installed at the inlet and outlet points of DHW systems. A contact temperature probe is attached to the piping to detect and transmit the water temperature.
Enless transmitters for Legionella monitoring can send their data to the cloud (using Sigfox and LoRaWAN technologies) or transmit temperature data locally to a building management system (using Wireless M-Bus and proprietary LoRa protocols).
The data can be accessed remotely and in real time. Action can be taken in the event of an alert indicating that the water temperature threshold has been exceeded, thereby preventing any risk of Legionella contamination.
