The front of the Pulse Pro has a light sensor and associated lens. Read this article for instructions on how to take spectral PAR/PPFD readings.

At the top is a hole if you want to hang the Pulse on a cord or loop. Read this article for placement tips.

It also comes with a wall mount and 3 screws to attach the wall mount.

The button is used for setting up the device, for resetting the device, and for taking advanced light readings.

The LED indicator on the side helps with troubleshooting connectivity issues. See this troubleshooting article for more information.

The expansion port is for future extra sensors that will plug into the Pulse Pro.

The temperature/RH vents are not protected from water or splashes. Make sure not to get any water on there.

The CO2 vent is protected by a waterproof, gas permeable membrane.

The power plug uses a 5v 3.5*1.35 mm barrel plug that is provided with the device. *The device needs to be plugged in to remain fully functional*

There's a cable routing system to help route the power cable either up or down. You can hang the device by the cable.
