Hey all,
I need to use sleep modes with Arduino Nano 33 IoT, but instead of waking up every x millisecond, I need it to wake up only when it detects, through a water flow sensor, that water is running through it. Is this possible? How would I read sensor values if the Arduino is sleeping? Thanks in advance.
Hi!
You have to set the "wake up" based on an interrupt event.
Take a look at the code in post #7 of this topic: https://forum.arduino.cc/t/iot-33-low-power/1082503/6.
In this case, pin 2 was used to wake up the 33 IoT from a button. It can be adapted to receive the change in the water flow sensor.
Thank you, this was incredibly helpful!
