An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

The block diagram of IR based automatic hand sanitiser dispenser is shown in Fig. 1, and its circuit diagram is shown in Fig. 2. It consists of an IR sensor module (IR1), transistor BC547 (T1), 5V ...

Fig. 3: IR transmitter circuit The block diagram of the infrared interruption counter providing an overview of the system is shown in Fig. 1. The astable multivibrator produces 36kHz frequency and npn ...

RF Sensor and IR Sensor are very popular sensors, which are used to transmit and receive the data wirelessly and they have a wide range of applications. We have developed many projects using RF sensor ...

The TSOP1838 is a miniaturized IR receiver module with a PIN diode and preamplifier assembled on lead frame; the epoxy package is designed as an IR filter. The demodulated output signal can directly ...

As mentioned in the block diagram, we need sensors to detect the line. For line detection logic, we used two IR Sensors, which consists of IR LED and Photodiode. They are placed in a reflective way ...

This project focuses on creating an automatic hand sanitizer dispenser using IoT, Arduino, an IR sensor, and a servo motor. The system is designed to provide a contactless and efficient solution for ...
