Scholars, students and engineers were asked to send in an innovative, new design idea for a sensor that measures a weather or hydrological variable and is both inexpensive and robust, the prize for the 10 best designs being an invitation to the workshop week in Akure, Nigeria in August 2014.

The 2014 Sensor Design Competition had a total of 16 entries. After the competition’s deadline on July 1st, 10 designs were selected for being original, inexpensive and robust. Among the designs, sent-in from universities all over Nigeria, were sensors for measuring rainfall, precipitation and humidity, sunlight, wind direction and wind speed, and temperature.

The objective of the TAHMO Sensor Design Competition is to design innovative sensors that measure a weather or hydrological variable and are both inexpensive and robust. These new sensing methods have to be resilient, low-maintenance and cost effective.

Competition outline
The TAHMO Sensor Design Competition will run from May till August 2014. Entries to the competition are open till July 1st. After the deadline the jury will decide which design teams will be invited to the final round, to be held in Akure, Nigeria from August 4-8. During the final round the teams will collaborate in a week long workshop to build a fully functioning sensor.

The 2014 Sensor Design Competition is open to participants from the ECOWAS region. Besides that, the competition is open to all who are interested, irrespective of profession, age or education.

Entry requirements
Deadline for competition entries is July 1st, 2014,  submitted to competition@tahmo.org. Your entry has to meet the following requirements:
·         – A .pdf file of max. 5 pages, describing your sensor design.
·         – Additional visual material of your design, preferably video and photos.
·         – A finished concept, supported by a list of the electronic parts needed for the sensor.

Winning contributions will be awarded with an invitation to the week long workshop at the Federal University of Technology Akure, Nigeria from August 4-8, 2014, with expenses related to transport, accommodation, and catering paid for. Also, the invited teams will get to keep the Arduino controller, that can be used to connect their sensor to the internet. A maximum of 2 people for each design team will be invited.
