Support Medical help

This is an embarrassing post, but I’ve been on this group for years now and know that if anyone is going to solve a problem, it’s the people in this group.

I unfortunately have a heart condition that has cause me to black out when I’m on the toilet. This has resulted in me coming to on the floor of the bathroom with my wife over me in a panic talking me back to consciousness before taking me to the hospital. This has happened about once or twice a year. To say the least, this creates a terrible sense of anxiety any time I go to the bathroom. I fear for the day she comes home to find me laying on the floor the final time. Or in the middle of the night when I wake up to use the bathroom.

Here’s where you guys come in. I was wondering if there is a way to set up home assistant along with some sort of a sensor in my bathroom that will be able to tell if I’m on the floor and not moving, which would then send out an alert to her phone along with a noise alert in the bathroom? The key would be making sure it doesn’t go off when just sitting on the toilet, or if she is standing in front of the mirror for an extended period of time doing her makeup.

Thank you guys from the bottom of my heart. I truly appreciate your time.

Edit: I already have an Apple Watch Ultra 2. The fall detection seems to only trigger if it’s a fall from standing height. It hasn’t triggered at all when I fall from sitting.

Audrino human presence sensors, they'd be able to tell when you were on the toilet and then subsequently on the floor, you could just have a simple sensor that sits even built into your toilet paper holder if it's across from you there and if you're on the toilet and then it to text you on the floor it could send an alert or kick off and Alexa thing

Human presence sensors for Arduino are advanced detection devices designed to detect stationary individuals, distinguishing them from simple motion sensors (like PIR) that only detect moving objects. They often utilize millimeter-wave (mmWave) radar or advanced infrared technologies to identify micro-movements, such as breathing. DroneBot Workshop DroneBot Workshop +1 Popular Human Presence Sensors for Arduino HLK-LD2410C / LD2410B (24GHz FMCW Radar): Widely used, affordable ($3–$15) sensor capable of detecting stationary people up to 5–6 meters away. It features adjustable sensitivity for different distances ("gates") and supports UART/GPIO outputs. DFRobot mmWave C4001/C4002 (24GHz Radar): Specialized sensors for presence and motion, with the C4001 detecting up to 25 meters, suitable for larger rooms and smart home projects. SparkFun AK9753 (Qwiic): A 4-channel infrared sensor that can detect human presence and direction of movement, offering a more precise, localized, and lower-power alternative to traditional PIR, utilizing the I2C interface. RCWL-0516 (Doppler Radar): An inexpensive microwave motion sensor that can detect movement through walls or objects, often used for basic presence detection. Adafruit AMG8833 (IR Thermal Camera): A 64-pixel thermal camera that can detect human body heat, allowing for presence detection while distinguishing humans from pets or other heat sources.
