I did exactly as shown , but as soon as I connect the battery the led glows and buzzer rings , and the IR sensors don't work . So what has to be the problem ? And also can make it right or I'll have to work on again?

[@erickcampos143]

Hey, do you know how the sunlight (or fluorescent bulbs) can influence in the circuit? I've been testing around these suspicious environments and the polarity of the IR sensor seems to be inverted. That's weird.

[@avikchakraborty3827]

It's not really inverted . in situations where there is a higher degree of IR the IR sensor will by default sense IR from the direct sources such as Sunlight or bulbs...now the IR from the reflection of obstacle is lower. Hence the logic seems to be reversed. Ideally in such situations go for ultrasonic sensors such as HC SR04

[@Kayv98]

Everyone this circuit does not work because it is WRONG. the photodiode must be placed in REVERSE BIAS. otherwise current will always flow through the diode and the voltage at the positive pin of the comparator (LM358) will always be higher than the voltage at the negative pin and hence the output will always be high. This means the IR emitted by the led will have 0 effect on the photodiode. ALSO WHEN MAKING YOU MUST MAKE SURE THE IR PAIR IS CALIBRATED FOR EACHOTHER. you cannot purchase a random photo diode and random ir emitter
