Lesson35- use SMS control relay and read temperature sensor

[admin]

send SMS text:

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!

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.

[admin]

because you have not installed PCF8574 arduino library. you can download this library zip file, unzip, copy the folder to your arduino library path.

I did exactly as you mentioned. But still no luck. Some where some thing is missing. I will whatsapp you a short video.

its giving me this error now. "Compilation error: DS18B20.h: No such file or directory"

[admin]

so you also need to install ds18b20 arduino library.

[admin]

this is ds18b20 library.

Now its giving me the following error\

In file included from C:\Users\saund\Documents\Arduino\libraries\sms-relay\sms-relay.ino:7:0:
c:\Users\saund\Documents\Arduino\libraries\DS18B20\src/DS18B20.h:5:21: fatal error: OneWire.h: No such file or directory
compilation terminated.

exit status 1

Compilation error: exit status 1

[admin]

you can install this  "OneWire" library in your arduino.

looks like its uploaded now. Is there any way to get the wiring schematics for this A8S module please? Thank you.

here is schematics for KC868-A8S: https://www.kincony.com/download/KC868-A8-PCBV1.4.pdf
