Virtual River Watch
Remote river monitoring system
Virtual River Watch has been developed to provide an affordable solution to provide river users and managers with up to date and relevant information on the current condition of a river or body of water. Using a range of current technologies the systems monitors the river through a range of sensors and then the data is uploaded to the internet where it is accessible in a number of forms.
The system uses Lorawan wireless technology to send the data from the sensors to a gateway at another location with internet access. This avoids problems with poor mobile internet and allows the system to be installed in remote locations and still take advantage of the internet for viewing and using the data. The wireless signal has a range of between 1 and 20km depending on terrain allowing the gateway to be installed away from the sensors in a location either with existing internet access or with 3g/4g mobile internet available.
The system consists of 2 parts, the remote sensor unit and the gateway.
The Remote Sensor Unit
This the radio transmitter and the processor for the sensors. The standard set of sensors provided with the system are;
Air Temperature, Air Pressure, Water Temperature, Water Level, Water clarity (Turbidity)
also available are sensors for;
PH Levels, Disolved oxygen Level and EC / TDS and other analog or digital sensors.
Wind speed and direction, Humidty, rain levels can also be integrated through a compatible weather station.
Gateway
The gateway is the device which receives the data and uploads it to the internet. The gateway uses either an existing broadband connection or mobile internet to connect to the internet. The collected data is sent using Lora radio to the gateway which then uploads it to the internet using The Things Network where it is then processed and stored.
The data is stored online in a MySQL database where it can be accessed through the internet from either a custom web page or integrated into a customers existing website or system.
The system also makes use of Cayenne which provides the user with an online console and mobile apps to view their data. The data can be shown as either numerical data or in graph form.

Apart from just viewing the data the user is able set up email or text notifications based on the state of any of the sensor data, e.g. if the river level rises over a set level then email or text warnings could be sent.
