## Description

Description: Condition:100% brand new and good quality Use: This 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. Features: Product Name: HC-SR501 Body Sensor Module Operating voltage range: DC 4.5-20V Quiescent Current: Trigger: L can not be repeated trigger/H can be repeated trigger(Default repeated trigger) Delay time: 0.5-200S(adjustable) the range is (0.xx second to tens of second) Block time: 2.5S(default)Can be made a range(0.xx to tens of seconds Board Dimensions: 32mm*24mm Angle Sensor: HC-SR501 Sensor Diameter:23mm(Default) Package Included: 5 X Stemedu HC-SR501 PIR Infrared Sensor Questions Q: What is the level output of these Q: I connected this to raspberry pi (5v) and it randomly activate without any movement. Is that normalQ: What is the delay adjustment and how to change it using the small dial" Q: Will it control 12 volt mini LED lights in my kitchen cabinets If you're interested in these questions, please contact us for the answers.

## Questions & Answers

**Q: Is there a place to add photo resistor in the board?**
A: It's configured with a photo resistor so it doesn't trigger during daylight.  In my application I want mine to trigger anytime someone enters the bathroom, so I jumped it out of circuit.  If you hold the board with the potentiometers up there is a row of resistors just below them.  The one on the right being the photo transistor.  The the body is clear, so it can detect light, that makes it easy to spot.  It's placement on the opposite side of the board than that of the sensor, kind of makes it worthless.

**Q: Is this affected by heat?  i have an am312 that throws false positives when my hvac turns on.**
A: Yes, the Passive InfraRed (PIR) sensor detects hot things moving. If your HVAC moves hot air in front of the detector, it should be detected.

**Q: What does it need to be powered up? like 5v 12v or ac voltage.**
A: Hello, the operating voltage range of this HC-SR501 motion sensor is DC 4.5-20V

**Q: What is the spacing on the 3 header pins? (Ground, Signal, Power)**
A: It is 2.54mm pitch on the 3 header pins.
