Conversion from DS18S20 to LM35 sensor
hello to you,
This is my first Arduino project and I have a few challenges, of course, I have even tried a few hours to locate the problem without success.
I have found a program that is perfect for my purposes, I want to switch from one DS18S20 sensor to LM35 when I have them in stock.
Here is my code
Servo and LM35 sensor
/ / Original John's HVAC Servo Controller - Version Final link http://www.instructables.com/id/Arduino-HVAC-Servo-ThermostatController/
Include <Servo.h>
/ / ENTER USER SETTINGS FOR TEMPERATURE Ranges & TIME IN THIS SECTION
int Need Heat = 22; / / If temperature is less than or equal to this number, heat vil turn on
int NeedAC = 24; / / If temperature is equal or greater than this number, the air conditioning vil turn on
long TimeToCheck = 300000; / / Enter milliseconds for unit two check. 1.000 milliseconds = 1 seconds. E.G. 300,000 million seconds = 300 seconds or 5 minutes
/ / END USER INPUT SECTION
float tempC; / / create variable two large the temperature in.
int tempCPin = 0; / / Attach vout two analog pin 0th
unsigned long hours;
long previoustime;
boolean heat = false;
boolean ac = false;
boolean off = false;
int NeedNothing1 = Need Heat +1; / / Tells the HVAC unit att om temperature range is mellem Need Heat & NeedAC, then kan turn itself off
int NeedNothing2 = NeedAC-1; / / Tells the HVAC unit att om temperature range is mellem Need Heat & NeedAC, then kan turn itself off
Servo myServo1;
void setup () {
Serial.begin (9600);
myServo1.attach (9);
myServo1.write (90);
}
void loop () / / code here fortsætter two replay nutil powered off.
{
tempC = analog read (tempCPin); / / read the analog value from the lm35 sensor.
tempC = (5.0 * tempC * 100.0) / 1024.0; / / convert the analog input two temperature in centigrade.
Serial.print ((byte) tempC); / / send the data til computer.
}
if ((hours - previoustime)> TimeToCheck) {/ / check temperature readings only once every "TimeToCheck" milliseconds (default is 300,000 milliseconds or 5 minutes)
previoustime = hour;
Serial.print ("Now Time");
Serial.println (time); / / prints timestamp at the moment the motors are triggered
}
if (tempC <= Need Heat && heat == false) {/ / if temperature is less than or equal to "Need Heat" (default is 24), turn on heat
myServo1.write (55); / / turns on heat ¡
delay (400); / / waits for the servo to get there
myServo1.write (90); / / returns servo to 90 degrees
Serial.println ("Heat er turned on!");
Heat = true;
ac = false;
off = false;
}
if (tempC> = NeedNothing1 && tempC <= NeedNothing2 && off == false) {/ / Tells the HVAC unit att om temperature range is mellem Need Heat & NeedAC, then kan turn itself off
myServo1.write (90);
delay (400);
myServo1.write (90);
Serial.println ("Unit er turned off!");
off = true;
Heat = false;
ac = false;
}
if (tempC> = NeedAC && ac == false) {/ / turns on the A / C
myServo1.write (130); / / servo moves back to 0 ¡
delay (400); / / waits for the servo to get there
myServo1.write (90);
Serial.println ("A / C er turned on!");
Heat = false;
ac = true;
off = false;
}
}
}
and here is the error
Servo_and_LM35.cpp: 4:1: error: 'servo' does not name a type

If anyone could help me with the code I would be grateful,
I am looking forward to testing the project as it will reduce my CO2 footprint, and I look forward to spreading it to others.
Kind regards Asger Linee, Denmark
ps. If my language is a little bad it is because I use a digital translator
