Brand: Stemedu

Description:

Condition:100% brand new and good quality
Use: This HC-SR501 PIR motion sensor can automatically and quickly open various types of incandescent, fluorescent lamps, buzzer, automatic doors, electric fans, automatic washing machine and dryer Machines and other devices, is a high tech products. Especially suitable for enterprises, hotels, shopping malls, warehouses and family aisles, corridors and other sensitive Sense of region, or for the security zone automatic lighting, lighting and alarm systems.
Also, it can work with Arduino or Raspberry Pi projects
As per the HC-SR501 data sheet, stops detecting ("detection range is shorter") as temperature approaches 30 degrees celsius (approximately 90 degrees fahrenheit).
These units have the through-holes to add a thermistor to improve high temperature performance, if one has a thermistor to add.
Easy to set up. Pins fit well into female Dupont wires for prototyping.
