    • RE: Motion Sensor (PIR) and Boost Converter

      Thanks guys, I have one of those modules I will test it out.

      I have been playing with a combination of 0.1uF and 10uF. It has been performing decently so far.

      Let's see.

    • Motion Sensor (PIR) and Boost Converter

      Hi,

      I hope you guys can help with this. I have a MySensor node running on 2AA batteries. It is a motion sensor with one of those cheap PIR modules.

      I am feeding the PIR sensor using 3.3V directly to the HIGH pin. So far so good up until here. The problem comes when I try to feed the PIR sensor using a boost converter 0.8-3.3v. With that configuration, the sensor throws tons of false positives.

      I attribute it to noise generated by the booster. I have tried adding a 4.7uF capacitor to the power supply but it hasn't helped.

      Any suggestions?

      Thanks!!
