Here is a clearer version of the specifications:

• The output port of the sensor module can be directly connected to the microcontroller's IO port and can drive a 5V relay.
• The module detects distances between 2 to 30 cm, with a detection angle of 35°. The detection distance is adjustable.
• Compatible with 3-5V DC power supply.
• A red power indicator light turns on when powered.
• The module uses an LM393 comparator.

Interface:

1. VCC: Connects to a 3.3V-5V external power source (compatible with 5V and 3.3V MCUs).
2. GND: Ground connection.
3. OUT: Digital output interface (outputs either 0 or 1).

Connections:

• VCC to VCC

• GND to GND

• OUT to IO (Input/Output) port of the microcontroller.

• The module includes 3mm screw holes for easy installation.

• Board dimensions: 3.1 cm x 1.5 cm (1.22" x 0.59").
