It uses an imported pyroelectric lens to detect human presence within a range of 2 to 7 meters .
Based on the alphanumeric format, most commonly corresponds to a replacement hardware component, specifically a replacement 4-Burner Ignition Module used in gas grills (often for brands like Nexgrill, Member's Mark, or Jenn-Air). hw-416-b
The is a highly versatile and cost-effective Passive Infrared (PIR) Motion Sensor Module , most commonly based on the HC-SR501 controller . It is a staple in the DIY electronics and IoT communities due to its reliability in detecting human presence and its seamless compatibility with popular platforms like Arduino , ESP32 , and Raspberry Pi . Key Features and Specifications It uses an imported pyroelectric lens to detect
Requires an initial warm-up period of 10 to 60 seconds before it can accurately detect motion. It is a staple in the DIY electronics
: The output goes low immediately after the delay time ends, even if motion continues.
Are you planning to use this with a specific microcontroller like an or Raspberry Pi ? PIR Motion Sensor HW416B - Tayda Electronics
Features dual onboard potentiometers to manually adjust sensitivity (distance) and delay duration (up to 300 seconds).
