Fc 51 Ir Sensor Datasheet Hot Link Jun 2026

Small footprint with a 3mm screw hole for easy mounting on robot chassis. Technical Specifications Specification Operating Voltage 3.3V to 5V DC Detection Distance 2cm to 30cm (Adjustable via potentiometer) Detection Angle Output Type Digital Logic (Low = Object detected, High = No object) IC Controller LM393 Voltage Comparator Current Consumption Pin Configuration The module typically features a 3-pin header: VCC: Connects to power (3.3V - 5V). GND: Connects to the common ground. OUT: Digital output pin connected to the microcontroller. Typical Applications

Digital Output (LOW when obstacle is detected, HIGH when not) Indicators: Dedicated Power LED and Obstacle Detection LED Comparator IC: LM393 2. Working Principle of the FC-51 fc 51 ir sensor datasheet hot

The OUT pin is meant to send a low-current digital signal to a microcontroller pin configured as an INPUT. If you accidentally connect the OUT pin directly to VCC, GND, or a microcontroller pin configured as an OUTPUT set to a conflicting state, it creates a short circuit. This causes excessive current to draw through the chip, heating it up instantly. 4. Defective Onboard Components or Manufacturing Flaws Small footprint with a 3mm screw hole for

The is an active infrared proximity module widely used in robotics, automated manufacturing lines, and DIY microcontroller projects . It utilizes a matched infrared transmitter and receiver pair to identify nearby objects without physical contact. OUT: Digital output pin connected to the microcontroller

The IR LED is designed to stay on. If it is high-intensity, it will generate heat.

20mA (Typical consumption rests around 30mA to 50mA depending on the status of the indicator LEDs)
