Here is below my Arduino code when I rises the temperature of lm35 the value and results show in decreasing and when I far away from lm35 sensor the value becomes increases.
float heat = 0.0;
adc1 = ads.readADC_SingleEnded(1);
heat = (adc1 * 0.1875)/1000; // convert ADC value into voltage
heat = heat * 100; //
