Wiring ESP8266 nodeMCU with HCSR04 Ultrasonic Sensor In this illustration we will going to wire the ESP8266 12E nodeMCU with Ultrasonic Raging Sensor HCSR04. As you can see the illustration below the sensor trigger pin is connected to D1 which is pin 5 in Arduino Board, and ...
12.HC-SR04 Ultrasonic Sensor The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. This sensor reads from 2cm to 400cm (0.8inch to 157inch) with an accuracy of 0.3cm (0.1inches), which is good for most hobbyist projects. In addition, this particular module com...
