In this post we are going to learn how to upload ultrasonic sensor (HC-SR04) data to Thingspeak using Arduino and generic ESP8266 Wi-Fi module and also using NodeMCU in the second half of this article.
20 de jul. de 2021 · This guide shows how to use the HC-SR04 Ultrasonic Sensor with the ESP32 board using the Arduino core. The ultrasonic sensor uses sonar to determine the distance to an object. We’ll show you how to wire the sensor to the ESP32 and provide several example sketches to determine the distance to an object using the HC-SR04.
Uploading data from Ultrasonic Sensor using NodeMCU to ThingSpeak. const char *ssid = "shen"; //Your Access Point or Personal Hotspot, cannot be longer than 32 characters! // The PING))) is triggered by a HIGH pulse of 2 or more microseconds.
4 de ene. de 2022 · Se realizará un circuito sencillo, y con las credenciales necesarias, podremos hacer una conexión hacia ThingSpeak para enviar los datos de nuestro sensor DHT11, para medición de temperatura y humedad.
Today I use D-duino control ultrasonic sensor and display distance successfully and upload to ThingSpeak at the same time.
This tutorial covers the following topics: Ultrasonic Sensor HC-SR04 Pinout. Wiring the Ultrasonic Sensor HC-SR04 to the ESP8266. Getting Distance to an Object Using the Ultrasonic Sensor HC-SR04 with the ESP8266. Displaying the Distance to an Object on a Display Using the ESP8266 and HC-SR04.
