What Celsicom AB does
Celsicom AB is a Swedish private limited company (Aktiebolag) founded in 2012 and headquartered in Halmstad, with additional sites in Varberg (market contacts, production planning, testing) and Lund (database and cloud development). The company designs, manufactures, and sells battery-powered wireless environmental sensors under the Celsicom Easy Connect line — including sensors for temperature, humidity, moisture content, CO2, radon, differential pressure, concrete strength, and ventilation parameters — paired with the proprietary Celsiview cloud platform for real-time monitoring, threshold-based alarms, PDF/Excel export, and API-based data integration into customer IT systems. Sensors communicate directly to Celsiview via built-in SIM cards on the NB-IoT network, eliminating the need for base stations or local power outlets; the legacy gateway-based Celsicom Connect system (CC202 base station) remains in the catalog.
The company operates a 100% channel-based go-to-market, distributing exclusively through authorized distributors in eight European countries — Sweden, Norway, Finland, Denmark, Iceland, France, Italy, and Germany — with Nordtec Instrument AB (Gothenburg) serving as the strategic Nordic distribution partner since 2014. End-customer use cases span construction and building (notably concrete curing via the TC603 sensor used by NCC), food safety and cold chain, HVAC and indoor air quality, cultural heritage preservation, and commercial facilities. Revenue is generated through two streams: hardware sales of the sensor portfolio and recurring cloud subscription fees for Celsiview data storage and access. Pricing is not publicly disclosed; all quotes and product/software support are handled by distributors.
The company is founder-owned and operated, with three co-founders — Stefan Carlsson (CEO), Per-Ola Stenborg, and Torbjörn Andersson — each bringing over 30 years of electronics and software/hardware systems experience. Headcount is in the 1–10 range, no external funding rounds are disclosed, and no parent company or institutional investor is identified in available sources. The company has continued to invest in product evolution post-2020, including the 2021 Celsiview v2 platform update and the April 2025 launch of the V600 ventilation-adjustment instrument.

Celsicom AB product offering
Product offeringCore offering
Celsicom AB designs, manufactures, and sells battery-powered wireless environmental sensors under the Celsicom Easy Connect brand that communicate via NB-IoT using built-in SIM cards, eliminating the need for base stations or power outlets. The sensors measure temperature, humidity, moisture content, CO2, radon, differential pressure, concrete strength, and ventilation parameters, and feed measurement data to the Celsiview cloud service, a browser-accessible platform providing real-time monitoring, alarm notifications, and PDF/Excel reporting. An API allows customers to integrate data into their own IT systems.
Product overview
Celsicom AB offers a unified remote monitoring platform consisting of the Celsicom Easy Connect sensor system and Celsiview cloud service. The Easy Connect series includes battery-powered wireless sensors (T600, TH600, TC602, T601B/C, TH601A/B, MM611B, DP600, V600, THC600B, TC603) that communicate via NB-IoT with built-in SIM cards. The complementary Celsiview cloud service provides data monitoring, logging, alerts, and reporting. The legacy Celsicom Connect gateway-based system (CC202) remains available. The company also develops proprietary wired and wireless sensors and hardware. An API enables customers to integrate measurement data into their own IT platforms.

Celsicom AB competitors and assessment
Company assessmentDirect peers
- Onset Computer Corporation (HOBO):
- Disruptive Technologies: Norwegian sensor company offering tiny battery-powered NB-IoT sensors for temperature, humidity, touch, and proximity, paired with a cloud platform. Closest direct competitor to Celsicom Easy Connect with similar NB-IoT-native architecture and recurring cloud revenue model.
- Elpro-Buchs AG: Swiss specialist in cold chain temperature monitoring and GxP-compliant data loggers with cloud software. Comparable to Celsicom in cold storage/freezer monitoring use case (overlapping with T601B/C sensors), serving pharma and food safety customers.
Broad incumbents
- Vaisala Oyj: Finnish industrial measurement company specializing in humidity, CO2, and environmental sensors with continuous monitoring solutions and cloud platforms. Competes with Celsicom in IAQ, cold chain, and humidity monitoring for industrial/cultural heritage applications.
- Testo SE & Co. KGaA: German global leader in portable measurement instruments for temperature, humidity, IAQ, and ventilation — overlapping with most of Celsicom's sensor portfolio. Much larger incumbent with broader product range, but largely handheld/portable rather than cloud-native wireless monitoring.
- Rotronic (part of Process Sensing Technologies): Swiss manufacturer of high-precision humidity, temperature, and CO2 measurement instruments with cloud connectivity options. Direct overlap on humidity and IAQ sensing with Celsicom's TH600 and THC600B sensors, primarily serving regulated industrial customers.
