Low Power IoT System Node Design

There are many sensor nodes in the environment like soil moisture sensors, temperature, pollution sensors, etc. The operation of these sensors is controlled by the microcontrollers that they are interfaced with. The main limitation of these sensor nodes is their battery life. If the battery life is just a few weeks, then the battery has to be replaced several times a year. The approach here is to minimize the current consumption of sensor nodes like the esp8266 Wi-Fi module that will be interfaced with sensors so as to work under very low power. The methods that need to be adopted so as to reduce power consumption of sensor nodes to achieve power efficient employment of Internet of Things (IoT) is discussed in this paper.
