LoRa analog sensor 4-20mA

Transmits data from existing measuring devices with 4-20mA output by radio
Hundreds of meters radio range in buildings
Up to 5 years battery life
Storage rooms, industrial environments, outdoor


The LoRa Analog Sensor 4-20mA has two separate 4-20mA inputs. It enables the wireless monitoring of all types of data (temperature, pressure, fill level, humidity, CO2, speed, brightness, opening, etc.) by collecting it from measuring devices and sending it to the LineMetrics Cloud via the LoRaWAN wireless standard.

The measured values are transmitted periodically at 10-minute intervals. Thanks to a special transmission protocol, maximum availability of the measured values can be achieved even at long range / in challenging environments. With the help of LoRa radio technology, significantly better penetration of storage rooms or storeys, for example, can be achieved compared to conventional technologies.

Tested for you: The best sensor on the market

This sensor has prevailed against comparable models in our test laboratory and has proven itself in practice.

Enorme Funkreichweite: Ganze Gebäude abdecken

Many kilometers of range outdoors or hundreds of meters indoors – no comparison with WiFi! More >

Battery-operated with approx. 7.5 years runtime

LoRa radio is very energy efficient. Depending on the quality of the wireless connection, the batteries will last for many years.

Plug and Play

Plug & Play integration into the overall system

It’s easy to obtain your first measurement data in just a few minutes thanks to the modular system – from the sensor to the cloud.

Your benefits with the LineMetrics platform

All-in-one: A complete system for room monitoring

1. Messwerte erfassen

2. transmit measurement data

The LoRa wireless gateway creates a wireless network for up to 1,000 sensors. The collected measurement data is transmitted to the cloud via mobile radio.


3. evaluate and alert

All sensors are managed and all measurement data stored in the cloud. Analyses, alerts and data integration via API are easily possible.

What is behind it? Find out what LineMetrics can do to help you easily obtain the measurement data you need.

Developing and operating an IoT-based monitoring solution is more complex than many people think. Here is just a small excerpt of what LineMetrics can do for you in the background so that you can easily and reliably obtain the measurement data you need:

  • Selection of international suppliers, supply chain management and price negotiations
  • Selection and testing of individual hardware devices, hardware quality management
  • Device and firmware management
  • Optimizations in terms of radio range and battery life
  • Database management
  • Connectivity management (SIM cards)
  • Security and encryption, including updates
  • Creation of instructions and support during rollout
  • 24/7 monitoring of the entire solution, support in the event of problems

Cloud platform: Analyze and process measured values

The LineMetrics Cloud allows you to create individual dashboards on which you can keep an eye on the data that is most important to you. Measured values can be displayed, combined and colored in the form of bars, curves, dial gauges, etc. This screenshot shows past and current measured values of the sensor:

Warning messages can be created for individual ranges/limit values and provided with a trigger delay. This means that no warning is sent if critical values are only briefly exceeded. A second condition for triggering a warning can also be configured.

Alerts can be sent by e-mail (see screenshot) or SMS. The recipient, subject and message can be easily configured individually.

Plug & play: obtain measurement data quickly and easily (< 3 minutes!)

The LineMetrics complete solution enables the solution to be commissioned via plug & play – without technicians, IT department, cable laying and network access. We will send you all the hardware with all accessories and simple commissioning instructions. The first measurement data can be analyzed in the LineMetrics Cloud within a few minutes. For questions, problems and tips, we have set up a comprehensive service center for you and can of course also be contacted personally at any time.

Instructions included

Specially created commissioning and installation instructions, printed and available online. Example >

Enterprise-ready: The flexible and future-proof business solution


Strict quality criteria

Our quality requirements include not only certified hardware, but of course also the security of your data. LineMetrics therefore relies exclusively on highly encrypted communication and multiple redundant servers in high-security data centers in the DACH region.


Efficient roll-out

A fast and cost-effective roll-out is possible with employees on site, no matter how many locations, no matter where in Europe. Everything required for commissioning and operating the solution is included – right down to the SIM card with LTE data package.

Professional support

A competent contact for questions, whether it’s about sensors, wireless connections, databases or dashboards. In addition, the help center, knowledge base and support ticket system are available 24/7.

API Schnittstelle

Simple integration (API)

Existing software and apps can continue to be used and automatically enriched with sensor data via API. This does not change existing processes and IT systems.
