Troubleshooting and Tips

PIR sensors are sensitive to power supply noise. If your DC rail drops or fluctuates under load (e.g., when a relay clicks on), add a

The module has and two jumpers :

The potentiometer labeled "Sensitivity" acts as a voltage divider into the BIS0001 chip. However, extensive testing shows that it does not significantly alter the physical range of the sensor in the way users expect.

If you place the sensor directly adjacent to an ESP8266 or an antenna-equipped microcontroller, radio frequency (RF) emissions can leak into the sensor's high-impedance amplifier lines. Keep a distance of at least 10–15 cm between the sensor and Wi-Fi modules. 6. Summary of Advantages hw-416-b pir sensor datasheet
