Context and challenges
• Improve water management to secure yields and optimize water consumption in regions where water is scarce
• Environmental data acquisition
How
• Completely autonomous Wireless Sensor Network (WSN) installed on a drip irrigation system with three soil matric potential sensors (Watermark) to monitor the water availability in the soil
• Data available in real time on the web (Figure 1).
• Alarm system by SMS when the soil dries out below a defined threshold
The Info4Dourou 2.0 research project : WSN to improve irrigation
Wireless Sensor Network
Features • Radio communication between field stations
transfer data to one base station
• Multi-hop network allows flexibility
• Base station transmits data via GPRS
• Web platform to access real-time data
• Various sensors can be connected
• Solar-powered and adapted to extreme conditions
• Alerts via SMS or email from web platform
• Local LED alarm
Towards the development of affordable stations for Sahel regions
Transfer of “Swiss made” technology
• A solution tailored to the specific needs of users
• Designed and assembled locally for affordability
• 3 different models will be developed to reach the widest user-population possible
• Development of low-cost sensors
Features of the 3 models Simple user interface Adapted to specific users’ needs Cost effective
Model 1 - local
Affordable for all
Local LED alarm
Easy to use
Model 2 – connected, isolated
Alarm via text message
Remote communication via GPRS
Data accessible on web interface
SMS
Model 3 – connected, network
Alarm via text message
Remote communication via GPRS
Data accessible on web interface
Radio communication between stations
SMS
Creation of a local manufacturing company in Burkina Faso
Dissemination of the technology and promotion by local actors to assure long term sustainability.
• Strong partnership with a well implanted social company in Burkina Faso
• Training of specialists for maintenance and dissemination
• Microcredits or Pay-as-you-go mechanism

Figure 2: Evolution of the soil water state with sensor-based and traditional irrigation. For sensor-based irrigation, yield is optimized and over-irrigation is avoided by irrigating only when the threshold is reached.
Threshold
Results
Figure 3: Mean agronomic indicators for different crops comparing traditional and sensor-based irrigation. The Water Use efficiency (WUE) or the ratio of harvest [kg] over water [m3] is greatly improved.
Challenges and improvement
1) Affordable stations for family farmers in Burkina Faso
• Reduction of communication costs
• Reduction of manufacturing and shipping costs
2) Interfaces adapted to different types of users : experts and non-experts
• Local LED alarm
• Remote communication via GPRS and SMS alarm
• Remote communication with data accessible on web interface
3) Potential future development
• Automatization of the irrigation (automatic valves)
• Other applications: Weather, wells, etc.
• Smart-phone app with additional meteorological and agronomic advice
