J3 LoRa+ GPS+Heart Rate + Blood Oxygen+Body Temperature + HRV(RRI) Smart Watch

  • BLE5.2+LORAWAN(868MHZ & 915MHZ ISM Band)+GPS;
  • Blood Oxygen Saturation (SpO2): Photoplethysmography (PPG) reflected light blood oxygen (red & light + infrared light)
  • Body Temperature: Support
  • Heart Rate: Support Static heart rate + dynamic heart rate
  • Blood Pressure: Support (not allowed, used with caution, not responsible for accuracy)
  • Heart Rate Variablity(HRV): 25Hz sampling rate (higher sampling rate can be customized) supports both broadcast data acquisition and Bluetooth SDK (API) acquisition
  • Stress Level: Support (the higher the value, the greater the pressure, and vice versa) – HRV based algorithm
  • Fatigue Monitor: Support (the data of the day before 8 a.m. every day) – algorithms based on heart rate / sleep / HRV
  • Pedometer/Steps: Support
  • Sleep Monitoring: support
  • SOS: Support the long press of physical keys for 5 seconds to broadcast SOS = 1, which is received by the base station, and the cloud platform makes the corresponding processing mechanism
  • Sensor data(Gsensor/PPG RAWDATA ): (Yes Optional)
  • With Lora Gateway:
  • 1. Support the uploading of vital signs data to the cloud platform through Lora base station (the default sending frequency is: send 1 packet of data in 5 minutes, including vital signs and GPS positioning data) (uplink data)
  • 2. Support SOS to report to the platform through Lora Gateway

5. iSmarch LoRa wristband detailed introduction

GPS/BD location:

High accuracy indoor and outdoor locating. We adopt lower power conmsuption GPS modula to support longer working time after fully charged. And LoRa wristband watch is biggest power capacity with over 650mah


Support BLE AOA locating

AOA positioning method is mainly to measure the angle of arrival between the smart watch and the bluetooth gateway. The bluetooth gateway is the starting point of the formation of the Ray must pass the mobile station, the intersection of the two rays is the location of the mobile station. The trick is to simply the estimated position of the watch (MS) can be determined by two buetooth gateway, and its location schematic is shown as below:
