Description
The HC-SR501 PIR Motion Sensor Module detects human movement using infrared pyroelectric technology. With a wide detection angle of up to 100°, it reliably senses motion within its range and triggers your project accordingly.
Operating on a wide voltage range of 4.5V to 20V DC, this low-power sensor draws less than 50µA in standby, making it energy-efficient for battery-powered devices. The compact module features a 23mm diameter lens and durable construction with glass fiber, plastic, and iron components.
Ideal for security systems, automatic lighting, and smart home projects, the HC-SR501 offers stable performance in temperatures ranging from -15°C to +70°C.
