HC-SR501
HC-SR501 Pinout
| Pin Number | Pin Name | Description |
| 1 | Vcc | Input voltage is +5V for typical applications. Can range from 4.5V- 12V |
| 2 | High/Low Output (Dout) | Digital pulse high (3.3V) when triggered (motion detected) digital low(0V) when idle(no motion detected |
| 3 | Ground | Connected to the ground of the circuit |
The HC-SR501 PIR Motion Sensor Detector Module allows you to detect motion. It's virtually often utilized to detect human movement within the sensor's range. It's also known as a "PIR," "Pyroelectric," "Passive Infrared," or "IR Motion" sensor.
Wide range on input voltage varying from 4. V to 12V (+5V recommended)
The output voltage is High/Low (3.3V TTL)
Can distinguish between object movement and human movement
Has to operate modes - Repeatable (H) and Non- Repeatable (H)
Cover distance of about 120° and 7 meters
Low power consumption of 65mA
Operating temperature from -20° to +80° Celsius

The HC-SR501 can be used as a stand-alone unit for most applications. The output signal can be used to control relays and LEDs. The HC SR501 module has the advantage of being a full ready-to-use module that does not require any extra components or platforms, such as an Arduino board or a Raspberry Pi board. You can use it on its own to detect motion using PIR sensors. Simply add power to the module and connect your device to the output and ground pins to use it independently. One thing to keep in mind is that because this PIR motion detector module is a low-current device, it cannot control high-current devices directly. You must utilize a transistor at the output of the PIR module to drive a high current module, and then you will be able to drive that high current device.
