KY-013 - Temperature Sensor Module

[@hansjuergenhaefner9622]

The circuit diagram is wrong, the Resitor R1 is between S and V , only then does it make a meaningful voltage divider.

I have an other one for you KY-005, same specie.

KY-013 R1 is for heating ITcom Academy,

do you have a sketch from this device?

[@deadend3758]

oh my god thanks!

I'm Sorry one correction. TF = (TC

[@etch4]

int ThermistorPin = A0;
int Volt_NTC;
float Vsupply = 1023.0;
float R2 = 7500; // R2 in Ohm change this !!
float logNTC, NTC, T, TC, TF;
//steinhart-hart coefficients
float c1 = 1.129148E-3;
float c2 = 234.125E-6;
float c3 = 87.6741E-9;
void setup() {
Serial.begin(38400);
}
void loop() {
Volt_NTC = analogRead(ThermistorPin);
NTC = R2 * (Vsupply / (float)Volt_NTC - 1.0); // NTC in Ohm
logNTC = log(NTC);
T = 1.0 / (c1 + c2*logNTC + c3*pow(logNTC, 3)); // Kelvin
TC = T - 273.15; // K-> C
TF = (9.0 / 5.0) * TC + 32.0; // C-> F
Serial.print("Temperature: ");
Serial.print(TC);
Serial.println(" C");
Serial.println();
Serial.print("Temperature: ");
Serial.print(TF);
Serial.println(" F");
delay(500);
}

Bit more clearer

[@WolfgangWittler1984]

Completely wrong: Schematics are wrong; the resistor is not used as overcurrent protection, but as voltage divider; the RPi has no analog inputs 😖

[@riverwang5482]

The circuit is clearly wrong. If it is that setting, reading will always be 0V.
