NODE Modular Radiaton Sensor Concept by George Yu is a PIN diode radiation sensor with adjustable sensitivity levels. It is only meant for low levels of radiation ranging from 0.1uSv/h to 10uSv/h. The Carbon Monoxide module is an industrial grade electrochemical gas sensor with a 0 – 400 ppm concentration range. NODE is iPad 3 compatible.
