- 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

  ![AHT20_BMP280 logo](https://github.com/peff74/PIR_YX-358A/blob/main/timing.png)

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

 ![AHT20_BMP280 logo](https://github.com/peff74/PIR_YX-358A/blob/main/MOD_1.jpg)

  ![AHT20_BMP280 logo](https://github.com/peff74/PIR_YX-358A/blob/main/MOD_2.jpg)

  

## Other Version 

  ![AHT20_BMP280 logo](https://github.com/peff74/PIR_YX-358A/blob/main/PIR_otherVersion.jpg)

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
