Do not place the Ruuvi sensors in an environment where operating temperature limits (-40C to +85°C) might be exceeded. This can damage the battery and electronics. Ruuvi standard batteries recommended usage temperature is -20C to +70°C. Use a Ruuvi extended range battery in a case exceeding these limits.
Ruuvi sensors use lithium coin cell batteries as their power source. Don’t let children, infants, or pets play with Ruuvi sensors. Seek immediate medical attention if you suspect that any person or animal has ingested a coin cell battery.
Do not place a Ruuvi in direct contact with water without its cover!
Do not apply vibration or shocks to the device.
