IR Proximity Sensor
When the module detects an obstacle in front of the signal, the green indicator light on the board level, while low-level continuous output signal OUT port, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases; counterclockwise to adjust the potentiometer to reduce the detection distance.

Frequently Asked Questions
1. What is an IR Sensor and why is it not visible?
- An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the red light was highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light. Anything that emits heat gives off infrared radiation
2. What are the types of IR sensor and their difference?
- There are two types of infrared sensors: active and passive.
Active infrared sensors both emit and detect infrared radiation.
Passive infrared (PIR) sensors only detect infrared radiation and do not emit.
3. What is the difference between PIR and IR Sensor?
- The IR sensors detect whether the light from the transmitter is emitted by an object or a person. Whereas, the PIR sensors detect changes in the levels of energy around the area.
If the PIR sensor is installed towards the changing environment, it may let off a false alarm due to the change in the way the air flows; however, IR sensors must be installed facing the motion.
IR sensors are usually only installed on the outside of properties, whereas PIR sensors are usually installed inside.
PIR sensors don't actually emit the infrared; objects give the sensor infrared rays. This differs from IR sensors, which do actually infrared.
