Technical Speciﬁcations
August 2021
RuuviTag is an open source sensor platform that measures temperature, air humidity, air pressure
and acceleration. With the Ruuvi ﬁrmware application, Ruuvi sensors continuously broadcast
sensor data at 0,8Hz and simultaneously log environmental sensor data at a 5 minute interval for
10 days. Sensors are updated by default at 0,4 Hz. This means that 2 consecutive broadcast
messages have the same sensor data. In most uses, battery lifetime normally exceeds 2 years.
