iPhone Sensor Detects If A Food Is Really Organic [Pics]
A device that plugs into your smartphone can measure chemical levels in various items.
Lapka is a series of four interchangeable sensors that allows your iPhone to measure how organic a food is. Users simply plug in the device through the smartphone’s headphone jack, and then lightly poke the food with the steel probe. The detector works alongside a special app to check for nitrate concentration, a chemical commonly found in fertilizers that are used on non-organic farms and in non-organic environments.
