Plug & play integration with the LineMetrics platform
Description
The LoRa temperature/humidity sensor is an advanced temperature and humidity sensor that relies on LoRaWAN® technology and is characterized by its high precision and robustness. This compact sensor is specially designed for use in harsh environmental conditions and has an IP67 waterproof rating, making it ideal for use in areas where precision and reliability are essential.
With a housing made of food-safe material, it can be safely placed in refrigerators, freezers or in contact with food and medicines. The sensor is characterized by its ultra-low energy consumption and is powered by built-in, high-capacity batteries, which enable a service life of up to 3 years without battery replacement.
Thanks to its compatibility with the Linemetrics platform, the LoRa temperature/humidity sensor can be used for remote monitoring and management in a variety of applications, including cold chain, agricultural greenhouses, office buildings, hospitals and factories.

Enorme Funkreichweite: Ganze Gebäude abdecken
Many kilometers of range outdoors or hundreds of meters indoors – no comparison with WiFi! More >
Battery-operated with up to 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 & 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. Record measured values
The battery-operated wireless sensor can be installed in any room. It reliably records all values and transmits them via LoRa.
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.

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.
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.
