Does the DFR 5V Proximity Switch work only with DFRduino board or can we program it using other microcontrollers such as the esp32c3??

Hello,

If you are asking about this product:

Then you may need to use it with a level shifter.
Because these sensors output 5V and the ESP32 has a pin withstand voltage of 3.3V.
