OBJECT SENSING WITH THE LM393
Sensor with a combined IR-LED and IR-receiver mounted side by side. The sensor can detect wheter a surface is light or dark. Suitable for linefollowing robots and optical counters. The trim potentiometer sets the light level where the output activates.
Supplies
SCHEMATIC DIAGRAM
Like all my projects, I share the schematic diagram so that you can do it yourself. The schematic diagram was designed in EASYEDA, a very professional and free electronic circuit design software, we can observe the electronic components that we use for this project and their respective values.
FUNCTIONING
IR Infrared Obstacle Avoidance Proximity Sensors consist of a transmitter that emits IR infrared energy and a receiver that detects IR energy reflected by the presence of any obstacle in front of the module. The module has the potentiometer that allows the user to adjust the detection range. The sensor has a very good and stable response even in ambient light or in complete darkness.
ELECTRONIC COMPONENTS
- 1 CI LM393 SMD
- 1 IR LED INFRAROJO
- 1 IR LED RECEPTOR
- 1 POTENCIOMETER 103(10K)
- 1 DIODE LED 0805 RED
- 2 RESISTOR 1206 SMD 10K
- 1 RESISTOR 1206 SMD 220 ohm
- 1 RESISTOR 1206 SMD 1.5K
- 1 PCB
FEATURE
Coverage Angle: 35°
Operating voltage: 3.3V – 5V
Detection range: 2 cm – 30 cm (adjustable with potentiometer)
Output level discrimination: Logic level outputs low when obstacle is detected
Active output level: High logic level outputs when no obstacle is detected
Current Consumption: 3.3V: ~23mA, 5.0V: ~43mA
Connection terminals: OUT: Signal from the medium, GND: Ground and VCC: Power
