The probe consists dual sensing technique - optical or magnetic. Therefore the user should select the one most suitable for the application.\n\n\u003cp float=\"center\"\u003e\n\u003cimg src=\"/doc/img/TFPROBE01A_connector.jpg\" width=\"48%\" /\u003e\n\u003cimg src=\"/doc/img/TFPROBE01A_sensors.jpg\" width=\"48%\" /\u003e\n\u003c/p\u003e\n\n\u003e This device was developed by [ThunderFly s.r.o.](https://www.thunderfly.cz) and is published as OpenSource hardware with a [GPLv3](LICENSE) license. It is commercially available, for a quote contact us by email at info@thunderfly.cz. Or buy it directly together with a [TFRPM01](https://docs.thunderfly.cz/avionics/TFRPM01/) sensor at [Tindie store](https://www.tindie.com/products/thunderfly/tfrpm01-drone-rpm-tachometer-sensor/).\n\n### Magnetic Sensing\n\nThe magnetic Hall-effect sensor mounted on the probe board can sense both directions of the magnetic field. The strength of the magnetic field is a decisive parameter for the probe's correct function. The magnetic flux is expected to be perpendicular to the sensor PCB surface. The detailed requirements of magnetic flux density are described in [AH3572 datasheet page 4](/doc/datasheets/AH3572-1483253.pdf).\n\nIn magnetic sensing, it is recommended to cover the probe in a black shrinking tube.  The covering blocks function of a reflective sensor.\n\n### Optical Sensing\n\nAn optical sensor is sensitive to the infrared reflectance of material (usually a rotating disc with marks).\nTo details see the [VCNT2020 datasheet page 2](/doc/datasheets/vcnt2020.pdf)\n\n## Hardware\nTFPROBE01A is designed as Open-Hardware (GPL v3). All documentation is located in this repository.\n\nThe TFPROBE01 is sold and shipped without a soldered header, because its orientation may depend on the customer's use. Connecting cable and two headers (one straight and one right-angled) are included.\n\n![Shipping content](/doc/img/TFPROBE01A_shipping_content.jpg)\n\n### PCB\n\n\u003cp float=\"center\"\u003e\n\u003cimg src=\"/doc/img/TFPROBE01A_top_big.png\" width=\"48%\" /\u003e\n\u003cimg src=\"/doc/img/TFPROBE01A_bot_big.png\" width=\"48%\" /\u003e\n\u003c/p\u003e\n\n#### PCB dimensions\n\n![TFPROBE01A PCB dimensions](doc/img/TFPROBE01A_dimensions.png)\n\n\n##### Optical and magnetic probe positions on PCB\n\n![TFPROBE01A optical probe position](doc/img/TFPROBE01_sensors_positon.png)\n\n### Electronic schema\n\nFull schema is available in [PDF](/doc/gen/TFPROBE01A-schematic.pdf)\n\n[![schema](/doc/gen/TFPROBE01A-schematic.svg)](/doc/gen/TFPROBE01A-schematic.pdf)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fthunderfly-aerospace%2Ftfprobe01","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fthunderfly-aerospace%2Ftfprobe01","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fthunderfly-aerospace%2Ftfprobe01/lists"}
