01Pro1 NB-IoT
NB-IoT is a low-power cellular technology designed for sensors that send small amounts of data. It supports up to 10 years of battery life and strong indoor coverage, making it well suited to monitoring devices installed in buildings.
// S-2Connect® platform
S-2Connect® Pro1
Three connectivity options. One product family.
Compare the Pro1 range and find the connectivity option for your indoor monitoring project. Review technical specifications, installation details and available documentation in one place.
- NB-IoT
- Cat 1 bis
- NB-IoT / Cat-M
// Overview
Indoor monitoring, clearly specified.
The documented Pro1 NB-IoT device measures temperature and humidity at configurable intervals and transmits the data over the cellular network. It runs on a built-in 10-year battery, gives installers feedback through a pushbutton and multi-colour LED, and receives firmware updates over the air.
- 01
Temperature and humidity monitoring
Periodic measurement of indoor temperature and relative humidity.
- 02
Configurable measurement and reporting
Measurement and transmission intervals set to suit the application and battery budget.
- 03
Battery-powered installation
Built-in 10-year battery, no mains wiring, with pushbutton and LED feedback for installers.
- 04
Cellular connectivity
Direct cellular reporting with over-the-air firmware updates. No local Wi-Fi required.
0102Pro1 Cat 1 bis
Cat 1 bis is a cellular technology that uses standard 4G LTE networks to connect IoT devices. It offers higher data speeds than NB-IoT, making it suitable for applications that need faster communication and larger data transfers.
03Pro1 NB-IoT / Cat-M
NB-IoT / Cat-M combines support for two low-power cellular technologies in one device, with Cat-M also known as LTE-M. This provides flexibility to use either network where supported.
The variants share the same product family; the photo shows the shared enclosure.
// Specifications
Compare the Pro1 range.
The NB-IoT and Cat 1 bis variants share the same specification, confirmed in the supplied datasheet; where a value is not yet confirmed for a variant it is marked "Contact us for specification".

- ¹ Battery lifetime is a specified estimate; actual lifetime depends on configuration and operating conditions.
- ² Tolerance figures describe the sensor manufacturer's production testing of the sensor IC, not complete-device accuracy. Contamination and long-term drift are excluded.
- ³ Humidity drift assumes no contaminant exposure and recommended operating conditions.
- ⁴ The recommended storage temperature supports battery lifetime. The survivable range is the stated limit the device can be stored at, not a recommendation.
