How Crowdsourced Apps can revolutionise weather monitoring

  1. 1. How Crowdsourced Apps can revolutionise weather monitoring Future Devices & Technologies SIG (#CWFDT) 27th March 2018 @3g4gUK
  2. 2. Sensors in Smartphones – iPhone X Location: Assisted GPS, GLONASS, Galileo and QZSS, Digital compass, Wi-Fi, Mobile data, iBeacon micro-location Sensors: Face ID, Barometer, Three-axis gyro, Accelerometer, Proximity sensor, Ambient light sensor ©3G4G Source: Apple
  3. 3. Sensors in Smartphones – Samsung Galaxy S9+ Connectivity: Wi-Fi 802.11 a/b/g/n/ac (2.4/5GHz), VHT80 MU-MIMO, 1024QAM, Bluetooth® v 5.0 (LE up to 2Mbps), ANT+, USB type-C, NFC, Location (GPS, Galileo, Glonass, BeiDou) Payment: NFC, MST Sensors: Iris sensor, Pressure sensor, Accelerometer, Barometer, Fingerprint sensor, Gyro sensor, Geomagnetic sensor, Hall sensor, HR sensor, Proximity sensor, RGB Light sensor Authentication: Lock type: pattern, PIN, password Biometric lock type: iris scanner, fingerprint scanner, face recognition Intelligent Scan: biometric authentication with iris scanning and facial recognition ©3G4G Source: BGR
  4. 4. What do the sensors do? ➢ Accelerometer: Accelerometers handle axis-based motion sensing and can be found in fitness trackers as well as phones—they’re the reason why your smartphone can track your steps even if you haven’t bought a separate wearable. ➢ Gyroscope: The gyroscope helps the accelerometer out with understanding which way your phone is orientated— it adds another level of precision so those 360-degree photo spheres really look as impressive as possible. ➢ Magnetometer: it measures magnetic fields and can thus tell you which way is north by varying its voltage output to the phone. ➢ GPS: GPS units inside phones gets a ping from a satellite up in space to figure out which part of the planet you’re standing on (or driving through). ➢ Barometer: measures air pressure: it’s useful for everything from detecting weather changes to calculating the altitude you’re at. ➢ Proximity sensor usually sits up near the top speaker and combines an infrared LED and light detector to work out when you have the phone up to your ear ©3G4G Source: Gizmodo
  5. 5. Realisation that sensors could generate weather information ❖ From OpenSignal Blog: ❖ Aggregating daily battery temperature readings to city level revealed a strong correlation with historic outdoor air temperature. (link) ❖ Fire spreading simulations, as well as fire danger rating systems, are largely based on two types of meteorological data: ambient temperature and relative humidity. Nowadays, some smartphones have incorporated sensors to measure both. (link) ❖ Other research on using sensors and crowdsourced data for monitoring environment (link) ©3G4G
