How it works
– The PIR sensor detects infrared radiation emitted naturally by humans and animals.
– When motion occurs within the sensing range, changes in infrared levels trigger the onboard circuit to output a digital HIGH or LOW signal.
– The Fresnel lens expands the sensor’s detection area, enabling a wide-angle view and improved sensitivity.
– Built-in potentiometers allow users to fine-tune sensitivity and output delay to match project requirements.
