Information Technologies and International Development is an interdisciplinary open-access journal that focuses on the intersection of information and communication technologies (ICTs) with the "other four billion" â€” the share of the world population whose countries are not yet widely connected to the Internet nor widely considered in the design of new information technologies.
First tests with E-5 soil moisture sensor and ECH2O handheld monitor (not strictly a datalogger since it doesn't store readings). An identical set was recently tested with Kenyan students by VeSeL member Cecilia Oyugi. It can relate to soil information, for example here.
Science for Humanity seeks to match scientific capability to human need. Through collaboration and innovation, Science for Humanity develops appropriate and sustainable solutions to alleviate poverty, increase social justice and realise economic benefit for poorer people.

Newick Primary School Year 4 class took part in their first activities as part of the VeSeL project, as a mobile resource kit, nearly identical to the one at Silanga School in Kenya, was delivered and used. This included a Macbook laptop, solar charging panel, and assorted small electronics. Photos of the hardware can be seen here.
Pupils created photo stories about a typical day at their school using the digital cameras delivered, which will be posted to the school's blog and used to communicate with Silanga School.
Based on our successful deployment at Kew Gardens VeSeL partner University of Leeds reports the following findings with regard to the sensor network operating autonomously in an agricultural environment.
The sensorsâ€™ precision was fairly acceptable, except for the light sensors. Solar radiation sensors were suggested instead. A soil moisture probe was added. The current housing of the nodes was found to affect precision of the temperature and humidity sensors. Better ventilation was suggested to resolve this problem.
VeSeL partner University of Bradford has successfully installed and set-up a database server connection for the wireless sensor network and radio community databases, which can be seen in this diagram.
This online database facility has been created for specific VeSeL user groups (i.e. those using the databases for information gathering; and those producing database results linked to the KMS). The KMS server provides two different kinds of database server, viz. mySQL and PostgreSQL.
New and enhanced functionalities
The team has also implemented the following functionalities of the KMS:
- Methods and tools for capturing, storing, organising and making accessible knowledge and expertise within and across communities;
- Interactive, sharing and collaborative facilities;

24th October 2008 â€“ Silanga Primary School
Upon my arrival at 11:00 AM, I went straight to Silanga Primary school and met the headmaster and later on the teachers. The headmaster mentioned that they are very happy with the progress made by the teachers and the students regarding ICT, and once again thanked VeSeL for assisting the school with the equipment.
