Thanks for your time! I’d like to substitute 4 DS18B20 temp sensors for the BME280 in the AsyncWebServer tutorial. Can you direct me to a resource? thanx, Pat

Hi.
Would you like to use four BME280 sensors?

To learn how to use BME280 sensor: https://randomnerdtutorials.com/esp32-bme280-arduino-ide-pressure-temperature-humidity/
If you want to use four sensors, you need to use an I2C multiplexer:https://randomnerdtutorials.com/tca9548a-i2c-multiplexer-esp32-esp8266-arduino/
It may also be useful to take a look at this I2C tutorial: https://randomnerdtutorials.com/esp32-i2c-communication-arduino-ide/

Let me know if this helps or if you need further help.
Regards,
Sara

Thanks to both Sara and William. Yesterday I noticed the ESP32/Ds18B20 tutorial posted by RNT. I should have seen it earlier. It looks like what I want except I want to publish to gauges. Wish me luck!
