Combined temperature and humidity sensors into one probe, this external probe can monitor two metrics at one time, reducing cost and improving efficiency.

There are two versions of the plug: Micro USB and Audio plug. The Micro USB port is suitable for our sensing device WS1 Pro and the Audio plug is designed for the GS1 device.

The measurements are transferred to the devices, displayed on the large LCD screen and synced to the platform via network. So you can access the data instantly on the screen or remotely view them via our app or web console.

Please notewhen connecting with our WS1 Pro device, only temperature readings can be displayed on the screen. While all the monitored sensor readings can be synced to our platform for your view via the App or the console. And the R&D team is proceeding on the development of new batch of screens so as to make both the temperature and humidity readings displayed on the screen.

Moderately waterproof and dustproof features enable you to deploy it in dusty greenhouse or somewhere highly humid.

This probe can only be connected to the lower USB port (USB2) on the WS1 Pro device.

The external sensors are disabled by default. Please enable them in the "Settings" page on the App or the console after inserting the probe into the device. In this case, the readings from the external probe are accessbile.
