[BK7231N / CB3S] AliExpress Generic PIR Sensor HW4008-W: Setup, Template, Features & Details
Purchased:from this link:
https://www.aliexpress.com/item/4000785415902...der_detail.order_detail_item.3.28fcf19cv5xMHt
Cost:
~$AUD16
(USB TTL converter to show scale)
Inputs:
1 x hidden switch marked "reset"
Power:
External micro USB connector
Internal 2 x AAA batteries
Template:
The board has a model number HW4008-W printed on it
The "reset" switch is actually just attached to P7, it is not a hardware reset.
Both inputs activate on pull to Gnd.
Flashing:
I used the BK7231Flasher Easy UART flasher after soldering RX/TX/3.3/Gnd wires.
I used an external PSU for 3.3v ( node MCU board powered from PC USB)
I had to set the UART speed to 115200 to avoid transfer failures
Flags :
I set Flag 10 - [MQTT] Broadcast self state on MQTT connect = On
I set Flag 37 - [WiFi] Quick connect to WiFi on reboot (TODO: check if it works for you and report on github) = On
Other Settings:
I have set both inputs to be "Door Sensor With Sleep" (DoorSnsrWSleep, with pullup)
I set startup value for 1 = 50. this makes the led illuminate dimly to show motion detection, with a small power saving.
I set startup value for 2 = 1. This seemed to be required to help door sensor driver.
After testing I set Startup Command text to "DSTime 10" to force shutdown for power saving reasons. (default is 60 sec)
Operation:
At motion detection I see first MQTT packet after 5-6 sec. unit goes to sleep about 5 sec later.
I would like to set a static IP address and see if that makes the initial connection faster but i cannot find the Command or setting anywhere.
[edit] I found the very obvious button on the main Config page... I'll update if it makes the first MQTT packet faster shortly.

Yes, both Quick Connect flag and static IP can increase the connection time to MQTT server. It should be about 5 seconds or maybe even less. We're constantly improving it. [Read more]
I have the same device, but for me this configuration isn't working... I dont understand, why p26 should be pwm?? i think it should be wifi_led. Why 2 DoorSnsrWSleep? (P7 abd P8) I tried this: P7 -... [Read more]
This device is battery powered and it's not TuyaMCU, which means we need to utilize deep sleep in order to preserve battery life. Otherwise batteries would drain in a matter of days. Using doorsensorwithdeepsleep... [Read more]
DoorSensor Driver only boot up wifi module? It does not change rel state? P26 is a Led. { "bt_pin":"7", "status_led_pin":"26", "rstcnt":"3", "basic_pin_pin":"8", "module":"CB3S", "jv":"1.0.1", "bt_lv":"0", "net_t":"180", "samp_type":"1", "basic_st":"1", "basic_pin_lv":"1", "samp_sw_pin":"14", "max_V":"3000", "min_V":"2400", "samp_sw_lv":"1", "status_led_lv":"1", "samp_pin":"23", "tamper_st":"0", "crc":"92" }...

Hi, from the photos above I believe I have the same device. It comes with battery state too. For me these settings have worked: - motion pin: p8 (dInput_n or DoorSnsrWSleep and Flag 42) (Channel 1) -... [Read more]
Hello, I also want to run this Device via micro USB, how did you disable the Deep Sleep? [Read more]
Hi there, if you have the same device, try setting "dInput_n" on P8 (or the pin your device has the motion sensor connected). This should keep the device awake. [Read more]
