The fourth and final winner was chosen by a public vote rather than the judging panel. The accolade went to The Zoological Society of London which is aiming to improve protection of threatened wildlife by equipping next-generation camera traps with automated sensors.
"We believe technology can change the world, and entrepreneurial nonprofits are a big part of that equation," said Jacquelline Fuller, director of Google Giving, in a blog post.
"We look forward to the impact these incredible organisations will have on the ground, and we applaud all of the nonprofits in the UK and around the globe that are using technology to make the world better, faster. Who knows where we'll take the Challenge next?"
In addition to the four overall winners receiving a cash prize, a further six finalists will be given 100,000 each in seed funding.
