Project file on the free design tool. Ir sensor module is a ir based proximity sensor. The circuit consists of an ultrasonic transmitter and receiver modules are used to detect the person. Here i connect more than one connection from one header pin.

You can see the circuit diagram at the end of this article. An infrared sensor circuit is one of the basic and popular sensor module in an electronic device this sensor is analogous to human s visionary senses which can be used to detect obstacles and it is one of the common applications in real time. The sensor can detect making touchless motion possible. Ir proximity sensor obstacle detector circuit on breadboard lm358 op amp projects duration.

Ir sensor for touchless motion and proximity january 2016 general description the is31se5000 is a low power reflectance based infrared light sensor with advanced signal processing and digital output. The following circuit diagram shows the circuit diagram of an automatic door bell system with the object detection. The is31se5000 uses one infrared led and 2 channel receivers which pick up the reflectance. In a proximity sensor an ir led and a photodiode is used to find a obstacles.

Com of relay module to supply voltage of doorbell. Ir stands for infrared which is a light with wavelength which is not visible to human eyes but cameras can see it. It is used in many applications such as tv remote and night vision cameras. Mainly it consist of an ir led photo diode lm358 operational amplifier ic variable resistor.
