Temperature sensor KY-013 (analog signal)
KY-013 is based on the principle of thermistor (resistance will change with the temperature of the external environment), which can detect changes in ambient temperature in real-time. Data could be sent to Arduino, and the sensor output data could be converted by simple programming.
