The Yoyo range of data loggers are simple, battery operated, yet highly robust data loggers for measuring multiple type of physical parameters depending on the model. They feature high accuracy readings in a small, very robust enclosure. The range include models with integrated measurement sensors, fixed external sensors and/or fully programmable input for interchangeable sensors. They are used to measure parameters such as humidity, light, voltage, current, pressure and temperature. Due to their small size, they can be placed almost anywhere (indoors or out) and left unattended to collect data on the local conditions. Example of applications are measurement and recording of temperature and humidity in agricultural, laboratory & healthcare and building environmental environments.
