[Installation for Generation 2 sensors](https://help.tector.com/getting-started#installation-for-generation-2-sensors) # Timber sensor setup ### **Timber sensor setup** Step 1: Power check - Sensors are shipped with the power ON by default. - If OFF, follow [this guide](https://help.tector.com/turn-on/off-the-sensor) to switch them ON. Step 2: Select installation location - Choose the spot on the timber surface where measurements should be taken. (Locations should be determined before installation. Follow sensor placements from the blueprint.) ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-09-33-07-0627-AM.png?width=670&height=59&name=image-png-Oct-08-2026-09-33-07-0627-AM.png) Step 3: Position the sensor - Align the sensor so the mounting holes face towards your target monitoring area. Step 4: Insert screws - Place two included screws into the mounting holes. **Sensors must always be mounted with screws to ensure valid measurements.** Step 5: Mount the sensor - Using a drill, fasten the sensor to the timber surface. ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-09-34-37-3264-AM.png?width=670&height=102&name=image-png-Oct-08-2026-09-34-37-3264-AM.png) Step 6: Optional top cover - Attach the protective top cover for weather protection (recommended for outdoor exposure). Step 7: [Register the sensor](https://help.tector.com/register-your-sensors) - Scan the QR code on the device. - Follow on-screen prompts to complete registration. ![](https://help.tector.com/hs-fs/hubfs/image-png-Aug-27-2025-12-35-35-1724-PM.png?width=445&height=280&name=image-png-Aug-27-2025-12-35-35-1724-PM.png) ### Installation specifications for sensors with insulated screws Moisture trapped deep within timber is often invisible from the surface. That's why we use insulated screws to measure moisture at a specific depth. With insulation covering the shank of the screw, readings come only from the exposed tip - giving you accurate data at the exact depth that matters.  ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-38-39-8254-AM.png?width=522&height=228&name=image-png-Oct-08-2026-11-38-39-8254-AM.png) When you are installing a sensor with insulated screws, always predrill holes for the screws with the following specifications: - the length of the insulation minus 20 mm (to compensate for the height of the sensor) - 1mm - 1.5mm thicker than the diameter of the screw (to avoid damaging the insulation) For example, if you have a screw that is 5 x 70 mm with 55mm of insulation, you must predrill a hole that is 6 to 6,5 mm in diameter and 35 mm deep. ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-39-36-2361-AM.png?width=670&height=231&name=image-png-Oct-08-2026-11-39-36-2361-AM.png) ### Installation specifications for sensors with insulated screws and WMC extensions When installing sensors with insulated screws and wire extensions, predrill holes at the designated locations using the following specifications: - Hole Length: Insulation length minus 5mm - Hole Diameter: 1mm – 1.5mm larger than the screw diameter Example: If you have a screw that is 5 x 70 mm with 55mm of insulation, you must predrill a hole that is 6 to 6,5 mm in diameter and 50 mm deep. ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-41-03-9185-AM.png?width=670&height=222&name=image-png-Oct-08-2026-11-41-03-9185-AM.png) When installing a sensor with an extension, it’s important to remember the accompanying metal and PVC washers in between the extension and the timber to prevent surface readings.  ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-41-49-9394-AM.png?width=670&height=118&name=image-png-Oct-08-2026-11-41-49-9394-AM.png)  As shown in the illustration below, install the components in this order: PVC washer first (closest to the wood), followed by the metal washer, the eye of the extension, and finally the screw head on top. Ensure the screws are installed perpendicular to the surface - angled installation can tear the insulation.  ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-43-00-0961-AM.png?width=503&height=234&name=image-png-Oct-08-2026-11-43-00-0961-AM.png) When installing the screws, remember to ensure that: - The head of the screw has contact with the metal plate in the mounting hole of the sensor or with the metal washers. - The screws are measuring within the same piece of timber and not separated by glue-lines ![](https://help.tector.com/hs-fs/hubfs/image-png-Oct-08-2026-11-44-40-4574-AM.png?width=627&height=144&name=image-png-Oct-08-2026-11-44-40-4574-AM.png) - [Getting started](https://help.tector.com/getting-started#main-content) - [Download](https://help.tector.com/getting-started#download) - [Prepare](https://help.tector.com/getting-started#prepare) - [Installation for Generation 2 sensors](https://help.tector.com/getting-started#installation-for-generation-2-sensors) - [Register](https://help.tector.com/getting-started#register) - [Finalise](https://help.tector.com/getting-started#finalise) - [General](https://help.tector.com/general) - [FAQs](https://help.tector.com/faqs) - [Hardware](https://help.tector.com/hardware#main-content) - [General Info](https://help.tector.com/hardware#general-info) - [Gateways](https://help.tector.com/hardware#gateways) - [Sensors for flat roof](https://help.tector.com/hardware#sensors-for-flat-roof) - [Sensors for monitoring on timber](https://help.tector.com/hardware#sensors-for-monitoring-on-timber) - [Product Compliance Certification](https://help.tector.com/hardware#product-compliance-certification) - [Software](https://help.tector.com/software#main-content) - [Sensors](https://help.tector.com/software#sensors) - [Groups](https://help.tector.com/software#groups) - [Reports](https://help.tector.com/software#reports) - [Alerts and alert rules](https://help.tector.com/software#alerts-and-alert-rules) - [Blueprints](https://help.tector.com/software#blueprints) - [Integrations](https://help.tector.com/software#integrations) - [Timber](https://help.tector.com/timber) - [Flat roofs](https://help.tector.com/flat-roofs) [![Tector-logo-black-RGB](https://help.tector.com/hs-fs/hubfs/Tector-logo-black-RGB.png?width=300&height=66&name=Tector-logo-black-RGB.png "Tector-logo-black-RGB")](https://www.tector.com/) **Denmark office:** [Tranevej 16, 2400, København NV](https://maps.app.goo.gl/6J7ifZTRXgVtrEyWA) [mailto:support@tector.com](mailto:support@tector.com) Copyright © 2024,
