Inside View: Building RuuviTags

Since the RuuviTag project was launched in 2015, we’ve also created customised products for clients who have requested something similar. On some of those projects, we have used Promistel Industries’ services and have been extremely happy with the cooperation with them.

Recently, we also decided to start building RuuviTags together and now it was about time to finally take a flight to France and go to see their campus.

The RuuviTag factory
RuuviTags are manufactured in France. I went to visit the factory to see the complete manufacturing process. Kimo is the CEO of the factory.

Promistel Industries is an electronics company founded in 1983 and is located close to Paris.

Their state-of-the-art production facility has everything that is needed to build embedded electronic products like RuuviTag:

Inside the factory
The factory specialised in SMD assembly (SMA).
Worker in the factory
After solder paste is applied on the board, the operator makes a quick visual inspection. The board also has to pass a 3D solder paste inspection before pick & place and reflow.
Assembly machine inside the factory
Promistel’s fastest assembly machine can place up to 20 components on a circuit board – in one second!
Assembly line that makes the RuuviTag
This is where the magic happens.
Freshly assembled RuuviTags
Freshly assembled RuuviTags on their way to the reflow oven. After the reflow, another 3D inspection has to be passed. After that, the units will be flashed (programmed) and their functionality (radio, buttons, sensors, LEDs) will be tested.

I need to say that during my 2-week visit to France, I was impressed about how clean and professional the factory was and how effectively they operated. I also noticed the staff had a high work ethic and their style of handling things was always professional and precise.

In the past ~8 years, I’ve dealt with numerous circuit board and electronics assembly factories around the world. Sometimes everything goes as planned but usually not. In this business, mistakes are expensive and can cause severe problems to customers. Especially, if deliveries get delayed without notice.

With Promistel, we can rely on their ability to deliver quality products in time.

RuuviTag is a Bluetooth sensor that monitors environmental conditions and sends the data directly to your mobile device. The Ruuvi Station mobile app allows you to view real-time accurate measurements and historical graphs. The app also provides customisable alerts to notify you of critical conditions, such as a melting freezer, excessively high bedroom temperatures that could disrupt sleep, or elevated humidity levels in your basement.

Temperature: °C, °F, K; typical accuracy ±0,2 °C @ 5-60 °C (±0.36 °F @ 41-140 °F).
Air humidity: RH-%, g/m3, dew point; typical accuracy ±3 RH-% @ 20…80 %. Range: 0-95 %.
Air pressure: Pa, hPa, mmHg, inHg; typical accuracy ±1 hPa. Range: 500-1155 hPa.
Motion: Movement counter. Counter is incremented when acceleration exceeds the threshold on any axis.

Operational Conditions

Operating temperature (with stock battery): -20 °C to +70 °C (-4 °F to 158 °F).
Absolute maximum operating temperature: -40 °C to +85 °C (-40 °F to +185 °F).
Housing: IP67, splash-proof, non-condensing location.
Battery: User-replaceable CR2477 (included). Supports extended operating temperature range battery CR2477T.
Battery lifespan: Estimated 12 to 24 months.
