Which sensor is HC-SR505?
HC-SR505 is mini PIR (Passive Infra Red) motion sensor module, which as the name implies used for detecting the motion of a body in front of it. The device works based on infrared technology and it can automatic control by itself with high sensitivity and high reliability.
Is PIR and IR sensor same?
Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots). Passive infrared (PIR) sensors only detect infrared radiation and do not emit it from an LED.
How do you use HC-SR505?
Pin layout First, make sure that the SR505 is provided with enough voltage: One of the Arduino’s GND pins must be connected to the SR505’s “-” pin. Next, the Arduino’s 5V pin must be connected to the “+” pin of the SR505. The remaining “OUT” pin returns either LOW or HIGH, depending on whether something was detected.
How can I reduce the range of my PIR Sensor?
Use masking tape around the sensor for a temporary adjustment and locate the area which works for your sensitivity. Then for a permanent solution remove the tape and just paint over the area where the masking tape was placed.
What kind of motion sensor is hc-sr505?
HC-SR505 is mini PIR (Passive Infra Red) motion sensor module, which as the name implies used for detecting the motion of a body in front of it. The device works based on infrared technology and it can automatic control by itself with high sensitivity and high reliability.
Can a hc-sr505 be installed in any system?
The device HC-SR505 can be installed in any system easily all you need to do is, connect the power to the module and receive the response from it. Let us consider simple application circuit of the device as an example. The device is powered from a DC power source and it can range from +5V to +20V and in the circuit we are using +5V power source.
What can a PIR motion sensor be used for?
Because of the minimum size and low-power operation mode, it widely used in various of automatic electronic equipment, especially battery-powered automatic products. Connect the PIR Motion Sensor to your Arduino/Crowduino power supply pin and digital pins.
