PS. chybí Ti cena
Ahoj díky za upozornění, myslel jsem že si případný zájemce vše dohledá na jejich webu. Dovolím si alespoň zkopírovat to, co uvádí výrobce:
Technical Details
Distance between beacons
Reach up to 50 meters in lab conditions
Recommended distance is 30 meters (Transducer4 to Transducer4 looking straight at each other and other transducers are off)
Coverage area
Reach up to 1000 m2 with the Starter Set configurations
Coverage for larger territories is similar to cellular networks
Location precision
Absolute: 1–3% of the distance to the beacons
Differential precision: ±2 cm
Location update rate
0.05–25Hz
Can be set manually
Depends on the distance between the mobile and stationary beacons (shorter distance — higher update rate)
Depends on the number of mobile beacons: for example, update rate of 25Hz for 1 mobile beacon will result in update rate of 25Hz/2 for 2 mobile beacons, and 25Hz/3 – for 3 mobile beacons, etc
Depends on the radio interface profile (500kbps vs. 38kbps)
Slightly depends on the number of stationary beacons — different than for mobile beacons
Power supply
Internal:
LiPol battery 1000mAh
Battery lifetime depends on usage
Stationary beacon with 16Hz update rate => up to 72h (tested)
Stationary beacon with 1Hz update rate => ~72h*16 => 1 month
Mobile beacon with 8Hz update rate – 12h (tested)
External:
microUSB – recommended for permanent use
Weight
Mobile beacon from Starter Set:
59 grams (including battery 1000mAh and housing and antenna 50mm)
27 grams (bare board w/o battery)
Beacon size
55x55x33 mm (with 50mm antenna: 55x55x65mm)
Ohledně ceny, kupoval jsem ji za 400$ plus nějaké poštovné. Prodám určitě levněji, za nějaký zlomek ceny, to záleží na domluvě. S pozdravem Pavel
