River Data

We offer a water monitoring system to return real time environmental data to users. This is a compact and competitively priced system using modern wireless technology and a range of sensors to monitor and record the water conditions throughout the day and night and upload this data to the internet.

The standard system enables hands off monitoring of;

Water Level

Water Temperature

Water Clarity

PH Level

Air Temperature

Air Pressure

 

Other sensors can be added to the system for weather data or other water monitoring sensors like oxygen level.

The system can be configured to send alerts via email or text if conditions reach certain levels like high water in a flood or high or low ph levels.

System

The sensor system uses LORA long range low power radio signals to send the data back to a base station where it is uploaded to the internet. The base station is usually placed in a location which already has internet access although mobile internet can be used if no other connection is available. The Base station has to be located within range of the sensors, this can be between 1km and 10km depending upon terrain. Longer ranges can be achieved in the right conditions. Each base station can handle the data from 100s of sensors. The sensors run from a battery and will hopefully last >6months at which point they need replaced or recharged. Battery levels are monitored by the system remotely. A solar panel can be added to increase the battery life. There is a wide range of other sensors available to expand the range of data collected. Data is uploaded through www.thethingsnetwork.org and can be viewed either through my website, a custom website/app or on https://cayenne.mydevices.com.

The system consists of the following parts;

1. Main controller box which includes the LoRa transmitter system, battery and air temperature, box temperature and air pressure sensors. This should be placed in a raised location near the river.

2. Water Level Sensor - this is a waterproof ultrasonic range sensor which calculates the level of the water. This should be placed over the water away from the bank.

3. Water Sensor box - this is used to protect the sensors which are in the water, water temperature, turbidity, ph and any other.

Parts 2 and 3 are connected to the Main controller box by cables. These should be protected from damage.

4. The LoRa Gateway - this receives the data from the controller box and uploads it to the internet using an available internet connection. This could either be an existing internet connection from a house or office near the river or using mobile internet. A power source is required for the gateway and mobile internet.

 

The Sensors can chosen depending on needs. The system can be expanded by adding other sensors at the main location or at other locations. For example a user may want to monitor the water level and ph of a number of feeder burns or streams entering the river or loch. This could provide warning of floods or alert the users of possible poluting events showing where and when they originated.
