Control if your plant needs some water, iphone notification
Posted: Thu Mar 26, 2015 7:28 pmHello all,
I think the title is clear enough to discribe the project.
The ESP8266 is connected to a moisture sensor (GPIO2- less $1) a led(GPIO0)
Checks every 6 to 8h
send an iPhone notification thru Prowl (2,99€) and blinks the led.
Here is my code.
I get 2 last things to resolve. any help apprecied.
1/ the last tmr.alarm doesn't start..
?? (tmr.alarm(2,1000,1,check_pin(4)); --GPIO2 )
2/ If the sensor is connected before to plug the battery or external power to ESP, I get a "crash". bad info...
