Overview
Square Comfort L measures temperature to ±0.2 °C and humidity to ±1.8 % RH, behind a smooth front with no visible holes. The vents sit in the back edges, at two opposite corners, and are hidden once mounted. It is 15 mm thick with a 4,000 mAh battery, for over ten years of operation even with frequent reporting. Where slim matters more, there is Square Comfort, 7 mm with 750 mAh.
Built-in memory means no readings are lost: when Square Comfort L has no LoRaWAN contact, it stores temperature and humidity in its data log and sends them when contact returns. That matters in vehicles, cold chains and places where coverage comes and goes. Wi-Fi geopositioning tells you where each reading comes from and flags a sensor that has been moved. IP63, for indoor and sheltered outdoor use, greenhouses and vehicles. Mount with the integrated adhesive, or with the optional screw kit.

Key features
- ✓No visible holes: A smooth front with the vents hidden in the back edges, discreet enough for a boardroom.
- ✓The large battery: 4,000 mAh in 15 mm, for the most demanding reporting profiles. Where slim matters more, take Square Comfort at 7 mm.
- ✓Data log built in: No readings are lost while coverage is gone: the sensor stores them and sends them over LoRaWAN when it regains contact, in vehicles, cold chains and basements alike.
- ✓Knows where it is: Wi-Fi geopositioning labels each reading with a location and flags a moved sensor.
Zubehör
- Square screw mounting kit: Zwei Klebeplatten, um jeden Square-Sensor dort zu verschrauben, wo Klebeband nicht ausreicht — hinter dem Gerät oder daneben. Details
