A range in four families: two gateways (the solar MSU-SG7 and the PoE MSU-G7), one master unit (MSU-MD7), two standalone LTE-M units (MSU-XD7 and its padlock version, the MSU-LD7) and two slave units (MSU-SD7 and the ultra-flat indoor SU-CD7). Every device carries the same 4 built-in sensors: temperature, light, accelerometer and 60 GHz radar. ### Can the sensors monitor telecom chambers being opened? Yes. Fitted on splice closures or on chamber covers, they detect every opening and send the alert in real time over LTE-M or LoRaWAN. Three reference architectures cover shared optical local loop ducts and operator-owned civil works. ### What is the difference between LoRaWAN and LTE-M? LoRaWAN is a long-range, very low-power radio network used to link the sensors to each other and to the gateway over several kilometres, with no subscription. LTE-M (and LTE Cat-1 bis) uses a mobile operator network, which sends data straight to the platform without any local gateway. ### Which detection modes can be enabled? Depending on the configuration, each sensor runs two detection modes at the same time, chosen from inclination, movement, vibration, infrared presence, change in light, H2S gas and cable drum unwinding. The modes are selected from the platform. ### How long do the battery-powered sensors last? Up to 10 years depending on the configuration, meaning how often measurements and transmissions take place. The MSU-SG7 gateway recharges from its solar panel, and the MSU-G7 gateway is powered over PoE or 12 V. ### Are the sensors suitable for outdoor environments? Yes: the MSU-SG7 and MSU-G7 gateways and the MSU-MD7, MSU-XD7, MSU-LD7 and MSU-SD7 units come in IP68 UV-resistant polycarbonate enclosures. The ultra-flat IP65 SU-CD7 is intended for indoor or sheltered environments. ### Where are DigitalWan sensors developed? DigitalWan sensors are developed in France. They comply with CE and RoHS requirements. ### How do I access the sensor data? Through the DigitalWan web portal and the Android and iOS mobile app: dashboards, real-time alerts, reports and indicators, remote device management and API access for your own tools. ### Is any network infrastructure needed on site? No. Devices fitted with an eSIM transmit over the mobile operator network (LTE-M in Europe, Cat-1 bis in Africa) with no local infrastructure. A LoRaWAN gateway remains an option for very large sites or areas with poor coverage. ### How do you detect a telecom chamber or splice closure being opened? By fitting a DigitalWan sensor on the splice closure or on the access covers. Depending on the configuration it combines two detection modes, for example movement and change in light, and sends a real-time alert to the monitoring platform. ### Is a gateway needed to monitor a telecom chamber? No, if LTE-M coverage reaches the chamber: one MSU-XD7 standalone unit per point to monitor reports directly to the monitoring platform. Otherwise an MSU-MD7 master unit placed nearby, on a mast or a bracket, collects the sensors over LoRaWAN and forwards the data over LTE-M. ### Where should the sensor be fitted on a splice closure? The MSU-SD7 goes inside the closure or is strapped around it with two cable ties. The very compact SU-CD7 clips behind a splice tray. ### How many sensors should be planned per chamber? The number of slave sensors follows the access points to monitor (covers, closures); the master unit is then placed inside the chamber or nearby, depending on radio quality and installation constraints. An MSU-MD7 master unit handles up to 5 slaves. ### Which other sites can be monitored? Data centres, technical shelters, confined spaces, technical buildings and warehouses, as well as wastewater structures and district heating networks. ## Blog articles Every article is also available as plain text: add “.md” to the end of its address (for example /en/blog/lorawan-vs-lte-m.md). ### Measuring tank level with a 60 GHz radar https://www.digitalwan.fr/en/blog/tank-level-monitoring-radar/ — 2026-09-22 60 GHz radar, ultrasonic or pressure probe: how to measure the level of a tank, reservoir or container remotely, and how to avoid false readings. - A 60 GHz radar measures distance without touching the product, through dust, vapour and darkness. - It suits tanks, reservoirs and containers; foam, condensation and irregular walls remain its main limits. - For aggressive liquids or readings under head pressure, a remote wired probe is a better fit: both can run on the same sensor. ### 10 years of battery life: what really makes it last https://www.digitalwan.fr/en/blog/iot-sensor-battery-life/ — 2026-09-20 How does a battery-powered IoT sensor run for ten years? The role of the lithium cell, transmission frequency, network choice and temperature, explained simply. - Battery life depends first on how often the sensor measures and transmits, not on the size of the cell. - Lithium thionyl chloride (Li-SOCl2) cells lose very little charge at rest, which makes a ten-year service life realistic. - A LoRa transmission costs far less energy than a cellular one: the network architecture directly shapes battery life. ### IP65, IP67, IP68: making sense of the IP rating https://www.digitalwan.fr/en/blog/ip-protection-rating/ — 2026-09-18 What does IP68 actually mean on an industrial sensor? A breakdown of the two digits, the common pitfalls, and how to choose between IP65 and IP68 on site. - An IP rating is read digit by digit: the first covers dust, the second water. - IP68 means dust-tight and resistant to prolonged immersion; IP65 protects against water jets, not immersion. - An IP68 enclosure does not remove the need for a properly tightened cable gland — that is where water actually gets in. ### LoRaWAN or LTE-M: which network for your IoT sensors? https://www.digitalwan.fr/en/blog/lorawan-vs-lte-m/ — 2026-09-15 LoRaWAN or LTE-M for an industrial IoT sensor deployment: range, battery life, cost and coverage. The criteria that matter, with three real-world cases. - LoRaWAN is a private radio network with no subscription, reaching 5 to 10 km, suited to sites where you can install a gateway. - LTE-M runs on a mobile operator network: no local infrastructure, but one subscription per sensor. - On the same site the two combine: sensors talk to each other over LoRa and a single device sends the data over LTE-M. ## Downloads - [2027 product catalogue (PDF)](https://www.digitalwan.fr/telechargements/catalogue-digitalwan-2027.pdf) - [MSU-SG7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-sg7.pdf) - [MSU-G7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-g7.pdf) - [MSU-MD7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-md7.pdf) - [MSU-XD7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-xd7.pdf) - [MSU-LD7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-ld7.pdf) - [MSU-SD7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-msu-sd7.pdf) - [SU-CD7 datasheet (PDF)](https://www.digitalwan.fr/telechargements/fiche-su-cd7.pdf) ## Contact - Quote request : https://www.digitalwan.fr/en/contact/ - Email : Contact@digitalwan.fr - Phone : +33 4 90 74 58 31 - Address : 2845 route de Banon, 84300 Cavaillon, France French version of this summary: https://www.digitalwan.fr/llms.txt
