Traditional Wireless Sensor Networks (WSNs) are usually powered by batteries. The paradigm of the Internet of Things (IoT) provides a vision with a wide range of applications including outdoor deployments. However, outdoor conditions bring up a new class of challenges and in particular temperature dependencies. Batteries are known to have a temperature-dependency in a way that voltage can vary of up to 500mV in a range of 40°C. This difference can be problematic to sensor nodes where the voltage is close to the allowed voltage operating limit. The so-called UnderVolting can be used to systematically power sensor nodes below the common voltage specification. This however can introduce a particular problematic case, where the battery can power a sensor node at a higher temperature (with higher voltage) and is not enough to power at a lower temperature. This effect can be used to optimize scheduling of tasks to run at higher temperatures if required.
