ESP32 Sensors and Web Server Project
Posted: Tue Feb 22, 2022 12:02 pm
Good afternoon:
I would like to ask some questions related to a project using ESP32 module and some sensors:
1. How many sensors I can connect at the same time to ESP32 module? (using different pins)
2. Which protocolwould you use? I2C?
2. I have selected the following sensors:
pH: GA0HOU-PH014
Temperature: DS18B20 or DHT11
Electric conductivity: DFROBOT GRAVITY ANALOG ELEC. COND. SENSOR
Rust reduction potential: DFROBOT GRAVITY ORP. SENSOR
Turbidimetry: DFROBOT GRAVITY TURBIDITY SENSOR
Do you have any better options?
3. Is it possible to instantly send the data collected by the sensors of the ESP32 module to a web server via Wi-Fi? And to a smartphone via BLE? (as the ESP32 module receives them, send them without previously having to store them)
Thank you in advance.
