Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

This sensor module is highly adaptable to ambient light. It features a pair of infrared emitting and receiving tubes. The emitting tubes emit infrared light of a specific frequency. When an obstacle (reflective surface) is encountered in the detection direction, the infrared light is reflected back and received by the receiving tubes. After processing by the comparator circuit, a green indicator light illuminates, and a digital signal (a low-level signal) is output from the signal output interface. The detection distance can be adjusted via a potentiometer knob, with an effective range of 2–30 cm. The operating voltage is 3.3V–5V. This sensor features adjustable detection distance, low interference, easy assembly, and convenient use. It can be widely used in robot obstacle avoidance, obstacle-avoiding vehicles, assembly line counting, and black-and-white line tracking, among other applications.
Module Parameter Description
1. When the module detects an obstacle ahead, the green indicator light on the circuit board illuminates, and the OUT port continuously outputs a low-level signal. The module's detection distance is 2–30 cm, and the detection angle is 35°. The detection distance can be adjusted via a potentiometer; clockwise adjustment increases the detection distance, and counterclockwise adjustment decreases it.
2. The sensor uses active infrared reflection detection; therefore, the reflectivity and shape of the target are crucial for detection distance. Black objects have the shortest detection distance, while white objects have the longest; small objects have shorter detection distances, and large objects have longer detection distances.
3. The sensor module's output port OUT can be directly connected to a microcontroller's I/O port, or it can directly drive a 5V relay. Connection method: VCC-VCC; GND-GND; OUT-IO
4. The comparator uses an LM393, ensuring stable operation.
5. The module can be powered by a 3-5V DC power supply. A red power indicator light illuminates when power is on.
6. It has 3mm screw holes for easy fixing and installation.
7. Circuit board dimensions: 3.2CM * 1.4CM
8. Each module is shipped with the threshold comparison voltage pre-adjusted via a potentiometer. Do not adjust the potentiometer unless absolutely necessary.
Module Interface Description
1. VCC: External 3.3V-5V voltage (can be directly connected to 5V and 3.3V microcontrollers)
2. GND: External GND
3. OUT: Digital output interface (0 and 1)
