All entries were judged on originality, feasibility and TAHMO criteria (i.e. no cavities, no moving parts, inexpensive and robust). The winning entries will be published on this website shortly.
All winners are informed by email. In the near future they will receive a 'Maker Package', consisting of all necessary materials to build their design. For questions, please contact firstname.lastname@example.org
Please find below more info about the TAHMO Sensor Design Competition. Please note that the competition is closed.
Current available sensors used in weather stations are not suitable for the TAHMO project. They are either too expensive, not rubust or they don't measure the variables we desire. The objective of the TAHMO Sensor Design Competition is to design a sensor that measures a weather or hydrological variable and is both inexpensive and robust.
The central idea is to measure climate and weather in new ways. This new way should be robust, extremely low in maintenance, and cost effective. One way forward would be to measure traditional weather parameters like air temperature, relative humidity, or sunshine, in new ways. Another way forward may be to measure non-traditional weather parameters such as lightning or dust. Either way, the measurement method would need to be robust, have no moving parts, low maintenance, and be cost efficient. For this competition, the focus lies on the sensors themselves and not on data communication. The central idea is to come up with new concepts.
We encourage you to be as innovative as possible in your design. Please don't feel limited by the access of materials you might have, as we will make sure that the selected design teams of Round I will receive a package with all necessary hardware and materials in order to actually build the sensor.

The TAHMO Sensor Design Competition is the first step towards building a TAHMO community. For TAHMO to be successful, local knowledge and expertise are absolutely essential. As the project is in the initital phase, still a lot of facets need to be addressed before we can actually start designing and building the weather station network. We therefore encourage everyone that is interested in TAHMO to join our community and join discussions on TAHMO-related topics. Are community is on Facebook and LinkedIn. All support is welcome. Together we can make TAHMO work!
The TAHMO Sensor Design Competition has a two-round entry process.
Round I: Submissions need only to comprise a description of the sensor. Click here for the entry requirements. From these preliminary submissions, 20 projects are selected by the Jury to go forward to Round II of the competition.
Round II: Winners of Round I will receive a kit consisting of all necessary hardware and materials needed to construct a prototype of the sensor they designed in Round I. The Jury will evaluate all prototypes and invite 10 winners to Nairobi for a multiple day workshop to test, tinker and integrate the ideas.
Round I is now closed. The deadline for submission was Thursday 14 March 2013. Winners of Round I will be announced before the end of March 2013.
Round II will run consecutively: immediately after the winners of Round I are selected and informed, they will be sent the kit. The deadline of Round II will be in June 2013. Participants of this round will be filled in on time on all the details. The final workshop in Nairobi will take place in August 2013.
In Round I, your design must meet the following criteria:
- The sensor must be able to measure a weather or hydrological variable. Be creative in your design, both in terms of parameters to observe and in ways of measuring them. We are looking for a sensor that measures either a standard parameter such as temperature and wind, or a less standard parameter such as dust or lightning. For this competition, the focus lies on the sensors themselves and not on data communication. The central idea is to come up with new concepts.
- The starting point is not so important as the outcome. You may want to build a sensor from scratch because that leads to a more robust and cost efficient way of measuring a parameter. Alternatively, you may want to take an existing IC/method and use it to measure something new or more accurately. An example of the first approach may be to measure the variance in humidity over time at high rates to estimate evaporation. An example example of the second approach would be to measure windspeed with a gasflow sensor used in cars. Of course we hope you will not copy these examples but work out your own.
- The sensor must be inexpensive to produce; i.e. less than $25 per piece when producing 20,000 pieces.
- The sensor must be robust; this means avoiding the use of movable parts as much as possible.
- Avoid any cavities in your design, as insects might use them as hide outs.
- The sensor requires zero maintenance for two years.
In Round I, your entry must meet the following criteria:
- The description of your design fits on maximum 5 A4 pages.
- The description includes up to 4 figures or tables
- The description includes a required executive summary of half page
- The format of your submission is preferably PDF
- Only entries in English are accepted
- On the first page of the entry, the first and last name(s) of the participant are clearly stated. When you are participating as a team, please include the names of all members.
- An entry can be submitted only after registration. Registration is possible until 1 March 2013. For a more elaborate explanation of the registration and submission procedure, please click here.
Winners of Round I will receive a kit consisting of all necessary hardware and materials needed to actually fabricate a prototype of the designed sensor. Therefore, we encourage you to be as creative and innovative as possible in your design.
Winners of Round II are invited to Nairobi for a multiple day workshop to test, tinker and integrate the ideas for a suitable sensor in the TAHMO project. All expenses regarding transport, accommodation and catering will be paid for by Delft University of Technology.
People from any country are eligible but we encourage especially African participants to join. In the TAHMO project we are particularly looking for local experience and local knowledge. We strongly encourage the formation of competition teams. Be aware that, when through to the final stage of the competition, only two members per team are invited to Nairobi.
