We have received many requests from customers who wish to use Wireless Tag in an outdoor environment. We have worked hard to try to make this possible.
We are pleased to announce that we have developed in partnership with Electronic Coating Technologies in Everett, WA an automated process to apply Silicone based conformal coating to the circuit board while precisely exposing the 3mm x 3mm humidity sensor IC's sensing surface, Piezo buzzer's side-slot for emitting beeping sound, and the coin-cell battery contacts, so as to retain its functionality as humidity sensor and lost item finder while providing protection against rain and condensation.
We have successfully tested the prototype; ten boards survived 2 weeks on balcony exposed to rain and morning dew. See live data for one at zip code 92603 (Yes, with direct sunlight, temperature can go up to 115°F at near 0%RH). Two uncoated boards we placed as control died after 2 days. This conformal coating is also expected to help tags survive in high humidity, condensation-rich environment such as some commercial freezers that are opened very frequently.
Over the next few weeks, we will begin larger scale production and starting from Wireless Tag Pro, gradually make available the variants with this rain proofing applied.
