This guide shows how to read temperature from multiple DS18B20 temperature sensors with the ESP32 using Arduino IDE. We’ll show you how to wire the sensors on the same data bus to the ESP32, install the needed libraries, and a sketch example you can use in your own projects. This tutor...
Arduino library for interfacing with Maxim temperature sensors like DS18B20, DS18S20, and MAX31850. Supports multiple sensors, asynchronous operation, and configurable resolution for precise temperature monitoring. iotarduinoesp8266embedded-systemsarduino-librarytemperature-monitoringds18b20sensorsonewiremulti-sensor...
Let’s first head over to themenuconfig. Open the ESP-IDF SDK Configuration Editor. Scroll down and open theesp32-ds18b20-exampleConfiguration. Here we can set the one wire GPIO number that will be used to connect with the data pin of the sensor. By default, it is set as GPIO4 which ...
Interfacing these sensors with Arduino, ESP8266 and ESP32 is very easy thanks to the Adafruit libraries. You can use our guides to learn how to use these sensors: BMP180: Arduinowith BMP180 Barometric Sensor ESP32 (Arduino IDE)with BMP180 Barometric Sensor BME280: ESP32 (Arduino IDE)with ...
