PIR Motion Sensor Module HC-SR501

PIR Motion Sensor Module HC-SR501

Regular price $1.64

Pyroelectric Infra Red (PIR) Motion Sensor Module for Arduino and Raspberry PI. Include 3 breadboard wires (Color of wires may be not equal as shown).

HC-SR501 is based on infrared technology, automatic control module, using Germany imported LHI778 probe design, high sensitivity, high reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic controlled products.

 

Adjustment:

  • (Sx) Adjust the distance potentiometer clockwise rotation, increased sensing distance (about 7 meters), on the contrary, the sensing distance decreases (about 3 meters). 
  • (Tx) Adjust the delay potentiometer clockwise rotation sensor the delay lengthened (300S), on the contrary, shorten the induction delay (5S)

Motiom Sensor Adjustment

Instructions for use:

  • Sensor module is powered up after one (1) minute, in this initialization time intervals during this module will output 0-3 times, a minute later enters the standby state.
  • Should try to avoid the lights and other sources of interference close direct module surface of the lens, in order to avoid the introduction of interference signal malfunction; environment should avoid the wind flow, the wind will cause interference on the sensor.

Include 3 breadboard wires (Color of wires may be not equal as shown).
