Introduction 36% of hand pumps in Sub-Saharan Africa do not
deliver water to their communities. To combat this,
the Intelligent Water Project is developing an auto-
mated, hand pump monitoring system that allows or-
ganizations to monitor the functionality of all of their
pumps in the field. The information generated by
IWP can be used to determine how much specific
pumps are being used and to generate warnings of
any pumps that are failing or have failed and are in
need of repair. The information is collected via SMS
in a database that can be accessed by authorized
technicians online, anywhere in the world.

How it Works
Real Time Clock and Calendar (RTCC): The system uses this external clock in case the sys-
tem loses power.
Sensors: The system has two sensors.
Accelerometer: Enables the system to measure how long it takes to prime the pump,
and the amount of water being pumped.
Water Presence Sensor: Senses when water is flowing from the spout.
Power Supply: Powers the system via battery. This battery is charged by a solar panel.
Global System for Mobile Communications (GSM): controls cellular communication and
transmits the data collected.

What Happened this Year?
Fixtures: Placed the box that holds the system outside to reduce overheating
and changed the material type to plastic for easier manufacturing
Improved mounting inside of the box for easier installation
Shrunk the water presence and accelerometer mount to enable
compatibility with the Afridev pump in addition to India Mark II pump
Hardware: Implemented premade GSM and power supply breakout boards
Integrated RTCC and its related components into our main board
Firmware: Developed code allowing the external RTCC and our PIC to communicate using I2C.
Encapsulated and cleaned up code
What’s next? Field Testing
Expand compatibility to the Afridev pump
CPU
Sensors
GSM RTCC
