Hi everyone,
I am planning to use a standard RuuviTag to monitor the temperature of my 2 EpiPens. The pens must strictly be kept between 15°C and 25°C. Currently, we are experiencing heatwaves around 40°C where I live.
Because space is extremely limited inside the cooling case next to the pens, the RuuviTag Pro is too large for my setup due to its mounting loops. The standard RuuviTag fits perfectly, but there is a major issue: I am using a FRIO cooler. FRIO cases cool through water evaporation, which means the internal environment is constantly at nearly 100% relative humidity with a high risk of condensation. My previous non-waterproof sensor (dotCool) died within a year probably due to moisture damage.
I read on the official product description that for immersion or high humidity, it is recommended to seal the Gore-Tex membrane with waterproof tape.
I only need to monitor the temperature and do not care about humidity or pressure readings.
My questions are:
If I completely seal the top hole (covering the Gore-Tex sticker) with high-quality waterproof tape or a drop of silicone, will it fully protect the internal electronics from the 100% humidity inside the FRIO case?
Will sealing this hole affect the accuracy or response time of the temperature measurements? Is there any risk of the sensor overheating or building up internal pressure?
Thank you for your help and advice!
Hi @Haig_Zsolt ,
Thank you for your question. A standard RuuviTag is IP67-rated, but it is intended for non-condensing conditions and is not recommended for continuous high-humidity environments where condensation can occur. Even the most rugged RuuviTag Pro sensor (2in1) enclosure is not fully gas proof and exposure to highly condensing environment for extended periods of time may possibly result condensation getting inside the enclosure over time, so we cannot fully recommend it.
For a medication application with a strict 15–25 °C requirement, we would also recommend using an appropriate backup or certified monitoring method rather than relying on a RuuviTag as the only temperature-safety system.
Dear Marko,
Thank you for your answare.
Zsolt
