Maximizing Performance with the HW-416B PIR Sensor: A Deep Dive into the Datasheet

void loop() if (motionDetected) digitalWrite(LED_PIN, HIGH); Serial.println("Motion detected!"); motionDetected = false; lastMotionTime = millis(); hw416b pir sensor datasheet better

Turning this potentiometer clockwise increases the detection distance. Delay Adjustment: Maximizing Performance with the HW-416B PIR Sensor: A

The is a compact Passive Infrared (PIR) motion sensor module, frequently used as a direct, higher-quality alternative to the common HC-SR501 . It uses the BISS0001 IC to process infrared signals into a digital output, offering better thermal stability and noise resistance than standard budget clones.
