LoRaWAN pressure & temperature sensor for level monitoringHigh-precision lorawan level probe With the Lobaro level probe, high-precision liquid levels can be monitored wirelessly via LoRaWAN at low cost and with low energy consumption. The sensors have a standard cable length of up to 15 meters and are connected via a digital bus; shorter lengths are also available on request. Power is supplied via the Lobaro box using a D-cell battery with a capacity of up to 19Ah. Due to the extremely energy-efficient system architecture of the Lobaro hardware, battery life of several years is easily achievable, even with a relatively frequent hourly measurement & LoRa transmission interval, for example. With the help of ceramic pressure sensors, level monitoring can be realized with an accuracy of just a few millimetres. For example, a 0..1.5 bar sensor is ideal for high-precision level detection of liquids with a depth of up to 15 meters. Other sensors support pressure ranges of up to 1000 bar and are therefore suitable for a wide range of industrial applications, such as tank level monitoring or pipe burst monitoring in district heating pipe systems. Internet-based monitoring of water level measuring points on rivers is another conceivable application. Together with the good penetration and range (up to 5km) of LoRaWAN and the low energy requirement, even hard-to-reach locations, e.g. at Weirs or groundwater level shafts can be monitored wirelessly. Please also contact us if you require our bridge with a mobile radio connection via NB-IoT (Narrowband-IoT) or LTE instead of LoRaWAN. We are happy to carry out such customer-specific adaptations as part of a cost-efficient adaptation of the hardware. The configuration is user-friendly via the free Lobaro Tool (Windows, Linux, Mac).   Background level probe sensor technology The level probe is queried via a digital interface as standard.

Temperature and humidity sensor with wireless M-Bus or LoRaWAN® radio interface The Indoor T+H Sensor records the temperature and relative humidity of indoor spaces. The sensor supports the user in optimizing the heating and ventilation behavior. The current temperature and humidity values can be read on the device display at any time. The data collected and stored by the device is transmitted to downstream recording systems using wireless M-Bus or LoRaWAN® radio technology. This creates transparency regarding the heating and ventilation behavior in order to be able to derive possible efficiency and optimization measures. This data can be used, for example, to prevent mold formation. The temperature and humidity measurement takes place internally in the device every three minutes. The average value for the last quarter of an hour is determined from the measured values, saved and added up in the register of the respective temperature or humidity range. The Radio transmission occurs every 20 seconds for wireless M-Bus and hourly for LoRaWAN®.
