Product Introduction
As the name suggests, the HW-488 infrared obstacle avoidance sensor is a type of sensor that uses infrared detection technology to detect whether there are obstacles ahead. Infrared detection technology is one of its key features. Infrared technology is characterized by high sensitivity, precise identification, and low cost, making it widely used in many obstacle avoidance detection applications.
Key features of HW-488 IR obstacle avoidance sensor
The HW-488 IR Obstacle Avoidance Sensor has advantages such as high sensitivity, long detection distance, small size, and easy installation. It is widely used in fields like intelligent robots, smart homes, and autonomous driving, providing reliable technical support for the obstacle – avoidance functions of intelligent products. Additionally, the HW-488 IR Obstacle Avoidance Sensor also features excellent stability and durability. It adopts high – quality materials and advanced manufacturing processes, ensuring that the sensor can still work stably in various harsh environments and is not easily damaged after long – term use. Meanwhile, this sensor also has the characteristic of low power consumption, which can effectively extend the usage time of intelligent products and reduce energy consumption.
HW-488 IR obstacle avoidance sensor pins
- GND = Ground pin, must be shared with the MCU ground.
- + = Voltage input pin (3.3–5V)
- OUT = Output pin, typically high level. When an obstacle is detected, the output pulse is low level.
- EN = Enable pin, active high. After installing the onboard jumper, the EN pin will be pulled to Vcc and remain enabled. After removing the jumper, the device can be enabled using the MCU’s output pin.

About HW-488 IR obstacle avoidance sensor
The core component of the HW-488 obstacle avoidance sensor is the NE555 chip. This chip can output a 38kHz square wave signal, which is used to light up the infrared LED light at the right end of the sensor. The key to detecting obstacles in front relies on the Vishay HS0038B infrared receiver module. This module can detect the infrared light reflected by nearby obstacles. The HS0038B module has a built-in 950nm external optical infrared filter and a 38kHz built-in electronic band-pass filter. The two work together to ensure that the module only receives infrared pulsed light of a specific frequency, thus avoiding interference from infrared light of other frequencies. However, it should be particularly noted that the HS0038B infrared receiving module contains AGC (Automatic Gain Control), which can quickly suppress continuous signals of any frequency, including 38kHz. Therefore, the 38kHz signal must be turned off regularly through the EN pin so that the AGC circuit can return to normal operation.
