1. How often do I need to change the PM sensor?

• TSI recommends replacing the PM sensor once a year.

Please note that critical firmware will automatically update after you delay three times, which is the industry standard. Also, yes, your BlueSky monitor will need to be connected to WiFi in order for the firmware to update.

14. What happens if I lose Wi-Fi connection to TSI Link Solutions in the middle of a firmware update?
