  • Aug 01, 2016 · This would not be a problem if I would attach the rain sensor to an analogue pin. However I did not have an analogue pin on my ESP8266-01. And I was not really interested in the water level. So I had to make the sensor work as a switch. As soon as a drop of water would fall onto the sensor it would have to give a signal to the ESP8266. Piece of ...
  • The ESP8266 module is a 3v device, but it's no wimp. It draws quite a bit of power. In fact, you'll probably need to make sure that your circuit's power supply can handle at least 1 amp of power.

It works with a combination of ESP8266 and ESP32 development boards and is composed mainly of 3 devices: 1. DEVICE 1: WEMOS D1 MINI PRO(New Version) + designed PCB (Need to be installed OUTSIDE) AND SOLAR PANEL This is the part which will be outside and it consist in one development board and the PCB. It is used to collect the weather data which will be sent to the Firebase of Google.
the current attachInterrupt code attaches the interrupt without clearing the interrupt flag. Since the flag can be set even when the interrupt is not enabled (not attached), this can lead to the interrupt handler triggering right away, even when the condition specified in the attachInterrupt call has not occured (certainly not after the
