Mini low cost PIR Sensor - PIR_YX-358A

• cheap +/- 1$
• small
• easy to use
• easy to modify

Details

• Working voltage:100-240V
• Load power: 40W
• Static current: ＜ 50μA
• Time delay: 45s
• Induction angle: 110 °
• Induction distance: 4-6M

know problem

Many devices have only a delay of ~20sec There are different versions of the PCB

kown facts

• all versions have the same, very simple AC/DC PCB
• all versions use the chip called SP015 A

The version that I got, possibly the newest one

• 230V side

• 3.3V side (C1 is accidentally missing ^^)

ONTIME MOD

technical details

how to mod, I use a 260K resistor and got around 45 secounds

Other Version

Here the resistor R10 is responsible for the delay. To change the delay

• 160K Ohm - 23 seconds
• 220K Ohm - 30 seconds
• 300K Ohm - 1 minute
• 470K Ohm - 3 minutes
