DIGOO 433MHz New Door & Window Alarm Sensor

[1technophile]

Here is some infos about an OMG compatible sensor the new digoo windows/door sensor.

It send 3 signals:

• Open
• Close
• Tampered (same as open signal)

It has an ON OFF switch and is delivered with the battery. Its form factor is quite compact compared to the previous tested door sensors

Here is the comparison with its main competitor the GS-WDS07:

433Mhz DIGOO NEW DOOR & WINDOW Sensor versus Golden Security GS-WDS07 comparison

We have currently 2 competitives window & door sensors that sit on the top of autonomy measurement: [image] GS-WDS07 (detailled tests) Affiliated link NEW DIGOO Window & door sensor (detailled tests) Affiliated link So as to make an advised choice here is a detailled comparison: Characteristics GS-WDS07 NEW DIGOO Range >25m ~13m Autonomy ~2y >5y Battery type AAA Lithium CR2450 Signal Open yes yes Signal close yes yes Signal tamper depend yes Signal low battery y…

Range estimation
With line of sights between the sensor on a vertical position and a sonoff RF Bridge I measure around 13 meters of range.

Power consumption estimation
When sending signal (open or close) 12mA during 1,6s
Sleep current 0.47uA continuously

Sleep current measurement 1mV = 1nA:

Action current measurement 1mV = 1mA:

Duration estimation
See the compatible devices list for the algorythm details
The result is 11439 days !!!

This calcul doesn’t take into account the battery discharge rate, but as it is a lithium one we can expect a best in class discharge. Making this door sensor a very durable one.

In PCB Where can we solder an antenna for to increase the power transmtion?

Hello, what is the range you are getting currently ?

[jbolanosg]

Hi, In open areas between 15 mts to 20 mts, My problem is a room where there is that to across two walls for that the signal to arrive to the sonoff Bridge. Today the signal does not detected for sonoff bridge. Other door sensor has antenna in Its PCB such as [GS-WDS07] but this sensor neither is detected for sonoff bridge in the same room. I have both sensors and neither is detected for sonoff bridge in this room.

When i relocate closer the sonoff bridge the signal the both sensor is detected without problem.
I am sorry for my bad english.

Thank you.

Hello,

Is it possible to locate a 2nd rf bridge in this room ?

@jbolanosg

sorry for my bad english

No problem, we are 2😉

I’m having the same range issue with rf switches. The gateway will miss about 1 in every 5 presses because a person was between the switch and the gateway (behind a wall). I tried soldering a 433mhz antenna to the transmitter with no improvements, which leads me to believe you’ll be better off improving the receiver antenna or its position, than improving the transmitter antenna. I’m no RF expert, so I might be talking nonsense, but that’s my experience at least. I got a heap of rf switches I can’t use because of that

With a similar door sensor and for the very same reason (intermittent loss of signal) I ended up installing a dedicated OMG RF gateway on each floor to improve reliability of my system.

Am currently testing this sensor, and I can see the open and close, but the values for tamper alarm and door are the same. So how can I distinguish between tamper alarm and door alarm ? Here is a small extract of the test:

568963 is open and 568969 is close, but trace shows sensor alarm and tamper alarm with the values. Any clues on how you can distinguish ?

@pensionado

Am currently testing this sensor, and I can see the open and close, but the values for tamper alarm and door are the same

I have exactly the same finding. I can just distinct between two codes (open/close) no matter if it’s caused by the tamper pin or by the reed switch.

Can some one confrim this? Maybe @1technophile?

Beside that I really like the build quality.

Downside of the long lasting battery is definitely the distance. My receiever is a esp32 with a srx882 module:

with a basic spiral antenna soldered:

Sorry, new users can only put one image in a post.

In my tests I have troubles to get a signal further than 5 to 6 meters even with a line of sight and no obstacles in between. Some one to comment on this?

You are right, I have modified the description. I confirm that the sensor send the same value when tampered or open.

With RFBridge I have measure around 13m outside with line of sight
