Deploying your Clarity Multi-Gas Module
This guide walks you through pairing, assembling, connecting, and field-deploying the Clarity Multi-Gas Module with a Clarity Node-S.
- You must charge, assemble, and configure the Clarity Node-S before connecting the Multi-Gas Module. If you haven't configured the Node-S yet, follow the Node-S deployment guide first.
- Not all Node-S versions can pair with the Multi-Gas Module. Check Node-S and module compatibility first. (Dashboard also checks compatibility for you during pairing — incompatible nodes are greyed out.)
- The Multi-Gas Module must be oriented correctly to stay weatherproof. The metallic mesh must point straight down toward the ground. Incorrect deployment can let in moisture and void the warranty.
- When not in use, store the module in its original packaging. If you need to return a unit to Clarity, ship it in the original packaging to prevent damage.

Pair the module in Dashboard
To use an accessory module it must be paired with a Node-S. Pairing tells the Clarity system the two are connected, so the module's data can flow to the Clarity cloud.
Pairing uses the guided Pair module wizard, which works the same way for every accessory module: open the Devices page, choose the module, pick a compatible node, and pair — or scan the module's QR sticker (the ID starts with M) to jump straight into the wizard with the Multi-Gas Module pre-filled. For the full click-by-click walkthrough, follow Pair a module on Dashboard.
- Configure the Node-S first. It must be set up before you can pair a module — see the Node-S deployment guide. The wizard only offers nodes that are compatible and available, so an unconfigured or incompatible node won't be selectable.
- You need an org admin or technician role. Without one, the Pair module button is disabled ("Requires org admin or technician role") — ask your org admin.
- Moving a module from another node? See How to unpair your module first.
What to confirm for the Multi-Gas Module
When the wizard shows the deployment guide cards and the Confirm before you pair checklist, they cover requirements specific to the Multi-Gas Module:
- Mesh faces down — the metallic mesh on the front must point straight down. Mount the bracket on the back (rotatable for poles or rails); the side flaps work for wall mounting. Wrong orientation lets moisture into the sensor and voids the warranty.
- Hang it 50 cm below the Node-S — so air flows freely between the two enclosures. The supplied cable is 1.5 m, so plan your spacing.
- Away from heat & exhaust sources — keep it clear of HVAC condensers, vehicle exhaust, smokestacks, and other point sources.
- Solar is enough — Multi-Gas runs on the standard Node-S solar panel; no EPS or mains adapter is required. Just make sure the Node-S itself is fully charged first.
Every item on the Confirm before you pair checklist must be ticked before you can continue — that you'll mount the module with the metallic mesh pointing down, hang it about 50 cm below the Node-S, and keep any HVAC, vehicle exhaust, or smokestack out of direct line of the inlet.
What if it doesn't work?
- The module isn't in the wizard's "In inventory" group. Confirm you're in the right organization and have the Technician or Org Admin role. If it shows under Already paired, unpair it first.
- The node I want is greyed out. It's either incompatible or already has a module of the same family — check Node and module compatibility.
- Still stuck? Email support@clarity.io with the node and module IDs.
What success looks like
The wizard showed the Module paired confirmation, and the Multi-Gas Module appears paired with your Node-S on the Devices page.
Check module status in Dashboard
After pairing, confirm the module is recognized and reporting. Open Devices (under SENSOR NETWORK) and stay on the Deployed devices tab.
- The Paired modules column lists every module on each node (e.g. Multi-Gas with its
M…ID). - Flip the Has modules toggle to show only nodes that have at least one paired module.
- Use the search box (top right of the table) to find a node, module, or location by ID or name.
- Each row shows health, last check-in time, battery, and signal inline; the ⋮ menu opens Diagnostics, Manage monitoring location, Open in Live Data, and Load historical data.
Assemble the module
Attach the mounting bracket to the back of the Multi-Gas Module. Your box includes a bracket and four screws.
-
Attach the bracket to the back of the module with the four screws. The bracket and hose clamps (not included) let you secure the module to a railing or pole.
-
Rotate the bracket to match the direction of your railing or pole, then tighten the screws.
- Wall or panel mount? Skip the bracket and use the flaps on the sides of the shield instead.
-
Plug the cable into the Multi-Gas Module and tighten it by hand using the knob.
What if it doesn't work?
- A part seems missing or won't fit. Check the In the box list at the top of this guide.
- Not sure about orientation. Follow the photos above; if still unsure, email support@clarity.io before mounting.
What success looks like
The Multi-Gas Module is fully assembled with all parts secured.
Connect the module to the Clarity Node-S
Run a connection test before deploying in the field, to confirm data is uploading to the Dashboard.
-
Make sure the solar panel cable is plugged into the configured Node-S body. When you plug it in, the Node-S plays the Node-S Power On sound and tries to connect to the Clarity Cloud.
-
Unscrew the cap covering the module port and plug the other end of the Multi-Gas Module cable into the Node-S body — align the cable pins and tighten the metal portion of the connector.
-
Once the module cable is connected, you'll hear the Node-S Power On sound again as the device resets.
-
Wait while the Node-S establishes a cellular connection. This can take 2–10 minutes depending on signal strength.
- If the node fails to connect, you'll hear the Node-S Connection Failure sound. Confirm the device is configured in Dashboard; if that doesn't help, contact support@clarity.io.
- If you hear the Node-S Low Battery sound, charge the device for at least 24 hours before proceeding.
- If the Node-S Connection Successful sound plays, proceed to deploy the device.
-
After a successful connection, the device communicates with the module. You'll hear one of:
- Successful Module Connection sound — the module is working properly.
- Failed Module Connection sound — check the cable connection between the Node-S and the module.
- Module Configuration Error sound — the Node-S isn't configured to accept modules. Make sure the module and node are paired in Dashboard, then unplug and re-plug the Node-S solar panel cable. If that doesn't help, contact support@clarity.io.
What if it doesn't work?
- I hear the Connection Failure sound (beep beep beep). Confirm the module was paired on Dashboard first, then re-seat the cable firmly.
- The module shows an alarm on the Dashboard. See Troubleshooting accessory module alarms.
- Weak or no signal at the site. See Troubleshooting a weak signal alarm.
What success looks like
You heard the connection sounds, and the Multi-Gas Module reports as healthy on the Devices page (Status dot on your node's row).
Deploy the Node-S + Multi-Gas Module in the field
The Node-S + Multi-Gas Module must be sited correctly to provide valid data:
- Make sure the module is correctly oriented: the text should be legible from the front, and the metallic mesh must point directly toward the ground. Failure to do so may cause water damage.
- Keep the module away from known sources of heat and moisture (e.g. an external HVAC unit) and from direct pollution sources (e.g. a restaurant's exhaust vent).
- Maintain a vertical gap of at least 50 cm (20 in) between the Node-S and the module for unobstructed airflow and to prevent water splashing between the devices in heavy rain.
After choosing the site:
-
Mount the Clarity Node-S to the designated pole, wall, or panel.
- To make installation easier, you can temporarily detach the module cable from the Node-S port.
- Use stainless-steel zip ties, hose clamps, or screws (not provided).
- Ensure the cable can reach the module once installed.
- More on Node-S deployment here.
-
Mount the Multi-Gas Module to the designated pole or wall.
-
Reattach the module cable to the Node-S body after both devices are securely installed.
-
Listen for these sounds in succession:
Congratulations! Your Multi-Gas Module and Node-S are online and uploading data. To see your data, check out how to access the data from your Clarity devices. The first reading typically lands in Dashboard within 2–20 minutes once the node uplinks; you'll find it on the location's card under Monitoring Locations or in Live Data.
What if it doesn't work?
- No module data after 20 minutes. Confirm you're viewing the right monitoring location on the Dashboard. See Confirming your device is uploading data.
- The metallic mesh can't point straight down here. Choose a different mount — any other orientation can let moisture in and voids the warranty.
- The battery keeps dropping. Check the Node-S solar panel isn't shaded and is angled toward the equator.
What success looks like
The device is mounted securely with the metallic mesh pointing down and a 50 cm gap below the Node-S, and Multi-Gas Module data appears on the Dashboard.
