Amazing, Thanks for such an informative video. Can you tell me if I can connect 4 flow sensors to a single NodeMCU and get the 4 different values at the same time? also how can the water volume data can be stored for future trend analysis.

please tell me why this error is occurring during compile: error: expected initializer before 'pulseCounter' void IRAM_ATTR pulseCounter() others mentioned getting this error but it has not been addressed in the tutorial link. thank you addendum: for anyone else with this issue, fixed by updating esp8266 to version 3.0.2 in IDE board manager

Good evening, on your thingspeak page, you've got a flow rate and volume graph. How do I get the volume graph to show total liters passed through the sensor?

Good project, but one thing I've noticed is that you wasted the water you measured. Please stop wasting water as water is precious and scarce. So please utilize it carefully. Thank you and wish you a great day ahead and a healthy day ahead. 🐈😿😸

@@alexandergraef8940 ESP GPIO are indeed 5V tolerant and always have been. They officially announced it several years ago too. Problems arise when reading analog signals on the pins as 3.3v is used as a reference. Use a LLS in that case. Digital use is absolutely fine and I myself use a range of 5V devices on ESP32 boards and have done for years. There's plenty of decent (modern and correct) write-ups online, including links to the comments made by Espressif.
