Helios – the multi-purpose IoT unit for industrial sensors
Helios connects pressure, temperature, pulse counters, and any industrial sensors to the wireless network – via LoRaWAN®, mioty®, NB-IoT, or LTE-CAT-M1. Pre-assembled or as a generic version for self-assembly.
Helios in practice
Four typical application scenarios in which Helios transmits industrial sensor data wirelessly.
Industrial measurement technology
Monitoring of pressure, temperature, and levels in production facilities, cooling, and hydraulic systems.
Building & HVAC
Wirelessly monitor HVAC systems, ventilation, heat exchangers, and energy centers—indoors and outdoors
Energy & Utility Networks
Pressure drops, leak detection, and condition monitoring in gas, electricity, and water networks.
Smart City & Water
Monitor well levels, groundwater, pumps, and urban infrastructure with hydrostatic probes.
One platform for many sensors
Helios combines industrial sensor technology with modern LPWAN wireless networks—flexible, robust, and energy-efficient.
Multi-Connectivity
LoRaWAN®, mioty®, NB-IoT, and LTE-CAT-M1 – choose the wireless standard that fits your infrastructure.
Universal interfaces
RS485, I²C, SPI, UART, 4–20 mA, Analog 0–10 V, Pulse counter, PT1000 – one device for many sensors.
NFC configuration
Conveniently set measurement and transmission frequencies, thresholds, and network parameters via NFC.
Battery operation
Low-maintenance power supply via 4× AA batteries – ideal for rollouts without cabling.
Power Management
Up to 12 V voltage in battery mode, up to 60 mA for external sensors – reliably powered.
IP67 & UV-resistant
Rugged ABS/PC housing for indoor and outdoor use – even under harsh conditions.
Preconfigured versions
Pressure, temperature (1–4 probes), pulse counter, PT-100/1000 – ready for immediate use right out of the box.
Generic versions
Can be customized with various interfaces for specific sensor applications.
