What is legionella?
● Around 60 types of infectious bacteria - intracellular parasite that multiplies in
the cells of the host
● The bacteria live and multiply in stale waters with a temperature of 20-45°C
● High risk environments - older water distribution systems where the water
doesn’t move around a lot, e.g. boilers, water containers, air cons
● Bacterial infection causes the Legionnaires' disease - acute lung pneumonia
that can last for weeks and is a high-risk disease for people 50+
● Most common source of outbreaks are cooling towers - bacteria spread through
aerosol, human-to-human transmission doesn’t occur

4.
Legionella prevention with IoT
● Legionella can be prevented with monitoring temperature - anything below 20°C
and over 45°C doesn’t facilitate a good environment for bacterial growth
● Water temperature measured through external sensors, regular reporting of
measured temperatures

5.
SimpleHW legionella prevention device
● Based on the SimpleIndustry (prototypes available now, final devices will be
ready in 6 weeks)
● IP67 compliant
● API 6
● Two external NTC sensors that measure temperature change without much
delay - sticked to pipes
● Specific legionella mode implemented
● 10 years battery life, 100.000 messages, Replaceable batteries
● Can be delivered with both removable and non-removable double-sided tape
● Can be mounted with screws as well

6.
Legionella mode description
● Regular uplink messages with data from both sensors
● Each sensor can be defined as Hot/increase or Cold/decrease (can be both)
● One or two pipes can be monitored
● The mode is based around a Flow
● Hot Flow, Cold Flow - when the temperature increases/decreases by x °C
● During flow, device measures temperature in a different interval
● Number of flows and maximum & minimum temperatures recorded
