CF816 Multiplexing
- ~0.4s one cycle (Start from port1 to port8)
My suggestion is to buy CF816 Fixed reader. CF816 and CF811 are basically the same, the main difference is that CF816 is using impinj E710 chip, which is more sensitive in reading and has a higher reading speed. CF816 also has more API commands than CF811.
CF800 is also using impinj E710 chip and has Android operating system additionally, which I think is not necessary to us. The API of the CF816 and CF800 are the same.
And buying two to four CF-RA8080 UHF RFID ceramic antennas to use with the Fixed reader, The gate size of the chicken house is around 30cm height and 27cm width. The ceramic has a size of 80*80*5mm, with circular polarization, its reading angle is 60 degrees forward. So it is possible to cover the gate size. But we can also go for a PCB antenna. For PCB antennas, I suggest CF-RA5005 UHF 5dBi Counter Antenna, also with circular polarization (120*120*6.5mm).

CF-RA6005 UHF Narrow Angle Beam Antenna fits the gate width perfectly, but it is not waterproof.
And two CF661 integrated readers, with a read range 0-6 meters. Prime reader and Fast reader are using the same SDK.

| 2.2 | | 12,28mm ⌀ |  14cm | 14cm | 14cm for the more curved surface was measured in the condition that pointing the tag either to right or left. And the detection was very bad when pointing the tag upward or downward. |
