ANGEEK 5 Pieces KY-013 Analogue Temperature Sensor Module for Arduino DIY Starter Kit

• Operating voltage: 3.3V-5V
• Module from KY-013 Arduino analogue temperature sensor measures the ambient temperature according to the resistance of the thermistor
• KY-013 analogue temperature sensor module consists of an NTC thermistor and a resistance of 10 k0.The thermistor resistance depends on the ambient temperature, the Steinhart hard equation serves us to maintain the exact temperature of the thermistor.
• Connect the power cable of the plate (center) and ground () with 5V and GND, respectively. Connect the signal (S) to the pin on the Arduino A0.
• Some boards KY-013 are marked incorrectly, if you get inverted readings (temperature drops when the sensor is heated) try to replace the signal((S) and mass ().

Description: The module is based on the thermistor (resistance increases with the ambient temperature changes) works, a sense of real-time to know the temperature of the surrounding environment changes, we send the data to the analog IO, then come down as long as we go through simple programming will be able to convert the sensor output data Celsius temperature values and displayed, it is still easy to use, it effectively, thereby widely used in gardening, home alarm systems and other devices. Method of application: And the general temperature sensor is the same, are three-line package, when we use the power cord connected OK signal output into the end on the line, because the module output is an analogue signal, we want to signal output terminal connected to the Arguing analogue IO on sampling, so as to correctly read the temperature value Test Code: Double thermister (int RawADC) Double temp; Temp = log ((10240000/RawADC) - 10000)); Temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * Temp * Temp )* Temp ); Temp = Temp - 273.15;// Convert Kelvin to Celcius return temp; Void setup. Serial.begin(9600); Void loop Serial.print (thermister (analogReadC). Serial.println("c"); Delay(500); Box contents: 5 x KY-013 analogue temperature sensor module
