ultrasonic distance sensor

Ultrasonic Distance Sensor ¶ The ultrasonic distance sensor allows you to use simple ultrasonic sensors like the HC-SR04 (datasheet, SparkFun) with ESPHome to measure distances. If no obstacle is there, then a 38us pulse is generated for Node MCU to confirm that there are not objects detected. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. If it receives them it produces an output pulse whose width can be used to determine the distance the pulse travelled. The HC-SR04 Ultrasonic distance sensor consists of two ultrasonic transducers. Before building the circuit let me explain what is an HC-SR04 Ultrasonic sensor?? Product selector Info; When light isn't enough. 99.
