Replacing the PM Sensors

Follow these steps to replace the PM Sensors. This guide assumes you have HDPE enclosure.

Step-by-step

• Open the enclosure

• Remove power from the sensors (both, USB and battery)

• Extract the SCK and PM sensors by removing the screws

• Disconnect the 6-way cable from the PM sensor

• Extract the PM sensor and replace it with the new one

• Connect back the 6-way cable and put the sticker from the previous sensor on the PM sensor (this ID is related to the Data Board)

• Put everything back together. No need to update anything else in the SCK. You are good to go!
