DiVes - LoRaWAN based pipe connection pressure monitoring

The development of IoT technology helps to integrate various monitoring devices into the infrastructure of production plants belonging to the water ecosystem. Existing older sensors and automation systems work well locally and in more closed, manufacturer-specific environments, but various devices using LoRaWAN networks are more system-independent and enable data collection and more flexible utilization of information to meet the needs of operators.

In the DiVes project, the pressure monitoring of the heating network is studied. The project monitors the Decentlab DL-PR21 device used with Veteli water works and the measurement data it produces.

The DL-PR21 can be directly connected to the G 1/4" threaded connection, or alternatively installed as such, for example, on the bottom of the water tank. The device currently sends the water temperature and pressure every 10 minutes, as well as the device's battery voltage. The measurement interval and data transmission interval can be changed remotely with a downlink message via LoRa network server.

The sensor is connected with LoRA technology to the project's network server, and from there the data is directed to the Dives data platform, which can be used to create visualizations and, for example, alarms based on limit values.
