#176 BLE Human Presence Detector using an ESP32 (Tutorial, Arduino IDE)

Cab BT radio estimate arrival signal direction? If one detector in both end of flat if it's not excluded downstairs neighbors, my child or me between those two radio, it's robber or police, which are pretty much equally bad so it's better trigger to send sms and start cameras recording..

Thanks for the NodeRed info, I hadn’t heard of it before

Combining PIR and microwave into one sensor detector might be an easier solution? That’s how home security systems work

Is it possible to use ble for precision tracking like air tags?
Do you have a video on uwb?

Now its time for a mmwave presence sensor :)

And aaa what if I don't use smart watch?

IED bumala bumala

Hello Andreas and thanks for your video!
Have you tested iBeacon with NRF51822 or NRF52810? Aliexpress has several options for tags on this chip. In theory, this should give a good result.
This question is especially relevant now for HomeAssistant users who want to set up automations when they change location - "ibeacon" integration was added not so long ago.
I found information about testing Chipolo One, but they did not achieve success there.
For me personally, work through the EspHome Bluetooth Proxy is of particular interest

This is from 2017, Have you addressed this problem since this video was posted?

Huge delay. You should send info over zigbee instead of reconnecting to wifi. C6 can do it

Thank, this gets me closre to a goal i have, id like to remind myself to not eat to much every time i enter the kitchen, but also id like to not spam me forever, do you have any idea on the range that the notification is sent?

Can it detect oui?

Could I use this to count people passing a location. But i have to estimate since not all phones would replay right?

How to send integer data from ble esp32 to phone using uuid can you please send the code to me

Can you get the esp32 Bluetooth to detect and or link to a Tile Keyfob tracking device or the app that tracks it?

i have wireshark and know very little about it... with all the bluetooth devices does wireshark have an auto detect app function..? also will it work with modicon modbus? thanks.

I know that Video is very old but today there is also the "olimex esp32-poe" available for 25Bugs. I would be interested in setting up a housewide network of such beacon snifferts collectiong their distances to a specific MAC on a Server(RaspberrPi) and calculate their position in different rooms.

Maybee it is possible to set up x nodes(sniffer) and create a Room-Map while going with the beacon through every room. (So afterwards it might be possible to identify each room)
In an ideal smart world I can go through the rooms with a beacon in my pocket and only lights in the coresponding room will turn on ;)
Too much?

You could add a video about esp csi human detection

What is that overhead LED light you have in your lab???

Hi Andreas, Like to check with you, are you able to teach how to detect the ibeacon battery status level and send notification to mqtt server? This could be a very interesting topic.

Hi Andreas. As always, a very cool video.

I have a question. I recently bought a small and cheap BLE iBeacon to play around with. The device is powered by a coin cell and features a push button. Is it possible to use such a device to trigger events on my Esp32? I would like to be able to use a small key-ring sized device to trigger a simple function on my Esp32. So I should like to know how to detect if the button on the iBeacon is pressed.

Hallo Andreas, gut dieses Video ist schon etwas älter, dennoch sehr interessant! Das ganze erinnert doch sehr an ein kommerzielles Produkt, nämlich "Happy Bubbles". Leider berücksichtigt dein Sketch kein Login beim MQTT-Broker. Das ist in aktuellen Implementierungen, z.Bsp. Home Assistant zwingend. Vielleicht gibt es irgendwann ein Update? Vielen Dank für deine tollen Videos und viele Grüsse!

I like this idea a lot. I’m thinking though I could use an esp32 for Bluetooth and an esp8266 for WiFi. Connect them together with uart. Then I could have a continuous stream of Bluetooth RSSI measurements being transferred to the mqtt. No switching on and off the different radios. With a few different nodes measuring the same RSSI should be able to do some triangulation.

What do you think about that?

Maybe it is the goal to use esp32 for Bluetooth that will be always in listen mode and will always search ble in your appearance, and esp8266 for wifi communication to mqtt server, serial (i2c) link between esp32 and esp8266.... I think it will work, I'll try to make some tests with this "topology"

hey Andreas,
ich habe deinen sketch erfolgreich kompelieren können, super arbeit... ich weiss der beitrag ist mittlerweile 4 jahre alt aber ich hätte da mal eine frage:
wäre es möglich das wenn der esp das gerät als abwesend erkennt sobald es ausserhalb der range < 80 wie in deinem skecht er auch das Topic 0 bzw Abwesend sendet ?
falls du dies ließt danke ich dir im voraus für die Hilfe..!

Hi Andreas, thanks for your great videos they are a source of inspiration.
I need a hint for my project. I have 5 ESP32 connected in a mesh via BLE.
I would like them to sense how physically distant they are from each other. It's for a game and I'm interested in approximately knowing their distance when they are between 10cm and 1 meter far apart.
Is this feasible? (PIR, Ultrasound and laser won't work as they don't distinguish an esp. RFID and Hall sensor don't have proper range)
thanks.

Thanks a lot ! I made an anti-theft key alarm using this .

Hi...do you sell the completed model? I would like to just receive a message each time someone enters a room..... if that person leaves then returns, I get another message etc....thanks

Thank you so much bro! Great video !!

hey, so I want to make a project that can detect human presence from about 5 feet away do you know anything I should do maybe combine a heat sensor and a thermal sensor

Hi Andreas,

Thank you so much for all your video´s. Really helping me out.
I was wondering about your git code.
On line 76 there is a value presented. The code writes -80. Is this where I can set the minimal signal strength for my BLE device? i.e. if I want my BLE device fairly close to the sensor I can change the value to lets say -50?

how to add user and password to the MQTT connection?

thank you boss. they mention "monitor" in docker. should we go in that route? how? please guide.

its always a pleasure to detect NEW FIELDS of application with your help and orientation. THANK YOU FOR YOUR HELP to so many makers.

Thanks for the great video. Do you know why my smart watch is not detected by the esp32 when it's connected to the phone? As soon as I turn the BT of the phone off and the watch disconnects, it's detected by the esp32. Thanks!

Hello there and thank you. I am looking to create social distancing alarm watches for children with audio/visual alerts based on the esp32 chipset. My question is whether or not the chipset has built in BLE to transmit proximity values in addition to what I already know it has the capability to do regarding reception of the signals. If it does, is there a significant latency period between switching modes between transmission and reception of signals, and if there is, can it be set to toggle between the two without absolutely draining a sub 1000 mAh battery in under 2 hours? Again, thank you so much. Great informative channel.

Hi, is it possible to use rssi to paired bluetooth device in order to turn on and off things.
I want to connect with serial bluetooth to my Android and if the signal strength is high then the switch on, if the strength is low then the switch off, so I don't have to click anything on my Android. How do you measure rssi of paired device and how to set the rssi treshold?

So i can not build a BLE bridge which broadcasts my received ble data over wifi? :(

use esp8266+module ble replace esp32 ?

Nice Video clip! Excuse me for the intrusion, I would love your thoughts. Have you ever tried - Norajon Proximity Packthread (do a search on google)? It is a smashing one off guide for getting money with paid traffic without the hard work. Ive heard some great things about it and my friend Sam finally got cool results with it.

I needed a lazy way to take attendance in my class and remembered this project. I have it working now, but initially had a problem compiling: Sketch too big. I couldn't find the option to re-partition the storage, but eventually thought of changing the board from ESP32 DOIT to ESP32 Dev Module. Now the Partition Scheme option appears under Tools and I could change to Huge App, and all was well after that. I wonder did the libraries grow so much in 2 1/2 years? And why does the DOIT board not have the partition option? More lessons learned...

Great video thanks. But why do we need wifi connection ?

This is not Human Presence Detector, this is device presence detector.

Hello there, I have one question. Is the BLE MAC address of ESP32 is discoverable while it is configured as BLE scanner?

can we try to measure RSSI value and based on that turn the lamp


if so how to do ?

Hi, do you have a tutorial on Wifi instead of BLE for sensing humans?

Did someone tested this with Phones?

hello, i don't understand english very well, but i would like to know if the light only goes on if you pass with your bluetooth device, if the answer is yes, i can find a way to understand

interesting, thank you for sharing
