From early smoke detection to liquid leaks and tank levels — one hardware platform, one data pipeline, zero wiring.

Photoelectric smoke and heat detection with an 83 dB on-site alarm and instant remote reporting. Optional CO₂/TVOC, human detection and camera.

Single contact sensing detects water, oils, coolants and chemicals. IP68 ruggedness and a 17,000 mAh battery for 16+ years of service.

Non-contact Time-of-Flight (ToF) ranging from 2.5 cm to 11 m — liquids and bulk solids. Tool-free installation, 4G direct-to-cloud, 15+ years maintenance-free.
Our sensors install in minutes, run for years on a single battery, and report straight to your server or platform.
We combine proven sensing technologies, signal processing and low-power design with a modular platform — enabling new sensor models and application-specific options as requirements evolve.
4G LTE, NB-IoT, LoRaWAN, Sigfox and WiFi variants share the same enclosure — pick the network, keep everything else.
Sleep currents down to 50 µA and high-capacity Li-SOCl₂ cells deliver 3–16+ years of life, depending on model.
Open TCP/UDP/MQTT reporting, network variants and optional sensing blocks — with private-label support for qualified projects.
Every BeginSense device follows the same simple pipeline — no gateways required on cellular models.
High-fidelity sensing elements detect smoke, liquid contact or distance changes in real time.
Event-triggered alarms are reported over 4G, NB-IoT, LoRaWAN, Sigfox or WiFi — typically within 30 seconds.
Open TCP/UDP/MQTT protocols connect directly to your server, platform or Sigfox backend. No lock-in.
SMS, app and platform alerts reach the right people.
