Project source: Cloned from GSM_Lock_v3
Description
i am usig on Smart lock, with gerkon on door.
also i use it on irigation system , where i connect flow sensor on D2, and I2C to Temp & himyd sensor AHT10. project was deploy
on waterproof encloser near water source. on water source was connected pump. When GSM command receive, AVR turn on relay, and
pump started irigation. flow sensor on D2 monitor water flow, if there is no water, it will turn on pump, and send sms. other input D3 can use
for other prposes.
