Abstract
Sensors which are connected to IoT board send data to either a local network or the Internet. The Internet of Things is the accretion of connected sensors. It is assumed that in the year 2025 approximately 75.44 billion devices are connected to the Internet of Things. In IoT greatest number of devices will be small sensors that send information about what they are sensing. Here we are going to design how an infrared sensor works with ESP8266 NodeMCU board and also implement these sensors to select object and measure the distance of the object by using ultrasonic sensor. These sensors provides both digital and analog output. Here we are performing only digital output which will be directly connected to a NodeMCU with Arduino platform to read the sensor output. Infrared sensor is used for object detection and Ultrasonic sensor is used for distance measurement.
