SKU: OT2043-A54 Artikelnummer: AB072 EAN: 4577243565130
Infraröd hinderundvikningsmodul.
Ger en 5V-signal när det inte finns några hinder och en 0V-signal när det finns ett hinder och den gröna LED:n tänds. Avståndet kan justeras med en potentiometer. Fungerar med 3.3V och 5V, har en röd power-LED.
Mäter avstånd till hinder på ett avstånd av 2-30cm och 35 grader med hjälp av infraröda signaler. Innehåller en infraröd sändare och mottagare.
Mått
Längd: 4,5cm
Bredd: 1,4cm
Höjd: 0,9cm
Så här kopplar du Infraröd hinderundvikningsmodul HW-201 till en Arduino UNO eller ESP32, med ett exempelsketch som du kan ladda upp direkt.
This project uses an HW-201 infrared obstacle avoidance sensor to detect nearby objects. When an obstacle comes into range, the sensor's digital output goes LOW, turning on the Arduino's built-in LED and printing detection alerts to the Serial Monitor. Adjust the onboard potentiometer on the sensor module to calibrate the detection distance.

This project reads the digital output from the HW-201 Infrared Obstacle Avoidance Module. When an object is detected within range, the sensor output drops LOW, lighting up the ESP32's built-in LED and printing an alert to the Serial Monitor. You can adjust the detection distance using the potentiometer on the module.
