Continuing on with more terms, an EHS load is the power consumed in microwatts by the sensing, processing, and communications functions of the target application. Easy DesignSim Software is a free web-based simulation tool for Cypress' PMIC solution used to validate the EHS design, including the bill of materials, schematic, and EHS load. An Internet of Things device, or IoT device, is an everyday physical object, for example a home thermostat that automatically performs sensing, processing, and control functions, and autonomously exchanges data with servers on the Internet. Wireless Sensor Node is a sensor based IoT device, for example a weather station that monitors conditions such as temperature, humidity, and pressure and wirelessly transmits the data to a control unit, such as a PC or mobile device, to connect to the Internet.
