- The PIR Sensor has an Operating Voltage of 4.5 ~ 20VDC
- The IR Sensor has an Operating Voltage of 3.3 ~ 5 VDC
- The PIR sensor module provides an output "High" when a human body is detected within its range and an automatic Delay "LOW" when the body leaves its range.
- The IR Proximity Sensor has an Onboard detection indication
- The effective distance range of an IR Proximity Sensor Is 2cm to 30cm
- The IR Proximity Sensor has a preset knob to fine-tune the distance range
HC-SR501 PIR Sensor (Passive Infrared Sensor) + IR Proximity Sensor
The HC-SR501 PIR Motion Sensor Module allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to as “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion Sensor” sensors. The PIR Motion sensor module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens.
The PIR Sensor has a delay time adjustment Potentiometer and a sensitivity adjustment Potentiometer. Repeat Trigger Selection Jumper is also available. Compatible with Arduino, Raspberry Pi, NODE MCU, PIC, 8051, etc.
The IR Proximity Sensor module has great adaptive capability of the ambient light, having a pair of infrared transmitters and a receiver tube, the infrared emitting tube emits a certain frequency, encounters an obstacle detection direction (reflecting surface), and infrared reflected back to the receiver tube receiving, after a comparator circuit processing, the green LED lights up, while the signal output will output digital signal (a low-level signal), through the potentiometer knob to adjust the detection distance, the effective distance range 2 ~ 10cm working voltage of 3.3V-5V.
The detection range of the PIR sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy-to-use features that can be widely used for robot obstacle avoidance, obstacle avoidance car assembly line count, black-and-white line tracking, and many other occasions.
