2. turn on/off all relay:
all-on turn ON relay1-8
all-off turn OFF relay1-8
3. read current temperature value:
temper read DS18B20 temperature sensor data
4. digital input for sensor trigger output
a. if input1 trigger, (siren) relay1 ON -> 3 seconds -> relay1 OFF -> send SMS: door sensor is triggered,someone in the room!
b. if input2 trigger, (siren) relay1 ON -> 3 seconds -> relay1 OFF -> send SMS: window sensor is triggered,someone in the room!
c. if input3 trigger, send SMS: sensor3 is triggered,someone in the room!
d. if input4 trigger, send SMS: sensor4 is triggered,someone in the room!
e. if input5 trigger, send SMS: sensor5 is triggered,someone in the room!
f. if input6 trigger, send SMS: sensor6 is triggered,someone in the room!
g. if input7 trigger, send SMS: sensor7 is triggered,someone in the room!
h. if input8 trigger, send SMS: sensor8 is triggered,someone in the room!
here is arduino IDE source code:
I tried to upload this "sms-relay.ino" file to my KC868-A8S esp 32 module. But i keep getting the same error message call PCF8574.h: no such file or directory.
Can you please explain how to install this pcf8574 file first.
