I've been searching for wireless sensors that could track the following metrics:

  • Location (GPS)
  • Heart Rate
  • Head Movement
  • Length of Steps
  • Skin Conductance
  • Pavement location (relative location compared to the walking lane, needs to be more accurate than GPS, to measure distance from cars, other walkers..)

I was thinking of the E4 Wristband, with additional cameras to measure head movement and pavement location.

Any recommendation to other sensors I should consider? Maybe a group of 3-5 sensors that could carry all functions?

    Hi, I'm not entirely sure this is the best SE site to ask if you're just searching for specific sensors. There doesn't seem to be an IoT angle to it. – Helmar Dec 31 '18 at 15:58

    Yes, it does seem more suited to https://hardwarerecs.stackexchange.com/ As to head movement, I remember 5 years or more ago finding a few circa $100 "brain wave monitors" and *think* that I recall them detecting head movement, so you might want to Google in that direction. Power supply is going to be factor here – Mawg says reinstate Monica Jan 02 '19 at 09:26

    See, for instance https://www.overdriveonline.com/fatigues-fast-track-body-language-wearable-monitor-makers-see-inroads-in-trucking-industry-detecting-fatigue/ – Mawg says reinstate Monica Jan 02 '19 at 11:07

    Thanks for the comments! The project is IoT related, that's why I used this forum, but perhaps I should pop the questions in hardware-related networks. – Rotem R. Jan 07 '19 at 07:05

    See if you get any help here. If not, delete this question, and ask again over there. Meanwhile, Google for crowdsupply health monitor. I Saw a programmable BLE on Crowd Supply yesterday which had heart rate and steps, maybe more (I can’t dig it out, as I am at work). Also look at Kick Starter and IndieGogo, as that’s where you will find emerging new tech which might be of use. I doubt that you will get it all in one device, but a few combined might do it. – Mawg says reinstate Monica Jan 08 '19 at 09:06

Heart Rate Sensor The heart rate sensor is based on photo phlethysmography based on blood absorbing light, this is low cost sensor with reasonable accuracy

GPS Module GPS module has an accuracy of 2 - 3 meters, can also be used to measure speed, in combination of the below sensor (accelerator, gyro and magneto meter) accuracy can be increased

Head Movement, Steps Length, Direction Attaching the sensor to head can measure the angular acceleration and along with magneto meter can detect the direction of rotation

Skin Conductance GSR Sensors The galvanic skin response refers to changes in sweat gland activity that are reflective of the intensity of our emotional state, otherwise known as emotional arousal. The sensor can measure the magnitude not the mood like (happy, sad, etc) but can detect the intensity

Microwave Doppler Radar Wireless Motion Sensor Low distance (20 meters range) obstacle measurement sensor to detect objects

Hope this helps
