Hello there, Currently I am doing a school project about water quality. I have connected many sensors such as DF Robot's 5v pH sensor, 5v Turbidity sensor and a TDS sensor to a Ardunio Uno. I've also connected a I2C Lcd to the Arduino UNO to display what the sensors are showing. All of that works. …

I have problem to configure ESP32 as I2C-Slave. So, I have configured ESP32 as I2C-Master and UNO as I2C-Slave. The working sketches are given below ; where, ESP32 recognizes UNO as I2-Slave at slaveAddress 0x23. Connect your all 5V sensors with UNO and collect data from UNO by the ESP32 using I2C p…
