Using UltraSonic Sensor

IoT-based real-time distance monitoring using ESP32 and HC-SR04 sensor simulated in Wokwi

This channel stores distance data from an ultrasonic sensor using ESP8266 and sends alert when the object distance crosses the threshold. The Android app displays the live distance status.

Obstacle detection for blind people This channel stores real-time distance readings from an ultrasonic sensor used for detecting obstacles. Data is sent via NodeMCU to ThingSpeak.
