Disclaimer: Specifications are typical for modules sold under the HW-416-B label. Always test your specific module before finalizing a design.
| Feature | HW-416-B | HC-SR501 | |------------------|------------------|------------------| | Core chip | BIS0001 (or clone) | BIS0001 | | Voltage range | 4.5–20V | 5–20V | | Trigger modes | L / H jumper | L / H jumper | | Output voltage | 3.3V | 3.3V | | Availability | Lower cost, generic | Widely used |
Verdict: They are functionally identical. Use HW-416-B if it’s cheaper or available locally.
| Problem | Likely Cause | Solution | |---------|--------------|----------| | No output | Warm-up period | Wait 60 seconds after power-on | | Always HIGH | SENS too high | Reduce SENS pot counter-clockwise | | Always LOW | Delay too short or SENS too low | Increase TIME or SENS pot | | False triggers | Vibration, RF noise, or heat sources | Mount securely; add 100nF cap across VCC/GND | | Short detection range | Lens dirty or SENS low | Clean lens; increase SENS |
Understanding the internal architecture helps in reading the datasheet correctly. The HW-416-B consists of:
The key IC on most HW-416-B boards is the BISS0001 (or a clone like the HT7610B). Referencing the BISS0001 datasheet can give you deeper insight into the timing and sensitivity adjustment.
Because of its small size (roughly 32mm x 24mm) and low power consumption, the HW-416-B is the go-to for:

If you are designing a system around the HW-416-B, these are the numbers that matter:
The HW-416-B is more than just a motion detector; it is an energy-efficient trigger. While newer, more expensive "radar" sensors (like the RCWL-0516) can detect motion through walls, the HW-416-B remains the reliable workhorse for line-of-sight detection. It is cheap, tunable, and consumes so little power that it might just be the longest-lasting component in your next battery-operated build.
