Lesson35- use SMS control relay and read temperature sensor
#2

1. turn on/off one relay:

relay1-on    turn ON relay1
relay1-off    turn OFF relay1
relay2-on    turn ON relay2
relay2-off    turn OFF relay2
relay3-on    turn ON relay3
relay3-off    turn OFF relay3
relay4-on    turn ON relay4
relay4-off    turn OFF relay4
relay5-on    turn ON relay5
relay5-off    turn OFF relay5
relay6-on    turn ON relay6
relay6-off    turn OFF relay6
relay7-on    turn ON relay7
relay7-off    turn OFF relay7
relay8-on    turn ON relay8
relay8-off    turn OFF relay8

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.
