The DS18B20 is a digital temperature sensor manufactured byMaxim Integrated(formerly Dallas Semiconductor). It is one of the most popular temperature sensors on the market and provides fairly high accuracy (±0.
Getting started with Ultrasonic Sensor Arduino and Raspberry Pi Pairing Guide For this tutorial, we will be using theGrove Ultrasonic Distance Sensorand pair it with the Arduino and Raspberry Pi. For the first tutorial, we have the guide for Arduino. Scroll down for the tutorial on Raspberry Pi...
Adding a setup_sensor() function to main.cpp (or elsewhere). This setup function will add the sensor column names to the configuration message. The highest sample rate will be used when sending data out, regardless of if the sensor has an update. Adding an update_sensor() function to main...
This module is based on the AM412 PIR sensor [2]. Connection diagram The connection diagram of this device to the ESP32 is really simple, since we only need to connect the data pin of the sensor to a digital pin of the microcontroller, as indicated in figure 1. Figure 1 –Connection ...
How to use an HC-SR04 Ultrasonic Distance Sensor with Arduino 19 Comments The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how ...
And sure enough, when we click the 'on and off' button, the data on the OLED display also change and we also get a constant flow of data from the DHT22 sensor, which means ourWebSocket connectionis working smoothly. This marks the end of theESP32 WebSocket tutorial. If you liked...
