      Hi everyone,
      I need to adquire the yosemitech sensor to integrate with Mayfly datalogger, i am creating a multiparameter sonde for limnological variables.
      Specifically i need the yosemitech Y514-A (cholorophyll sensor)
      Does anyone know where to buy them in the USA?
      Does anyone know of any other low cost alternative?

      Hi Cesar,

      We (mostly me and @aufdenkampe, I think) have been purchasing them directly from Yosemitech because they are so darn cost-effective without compromising quality. Currently they are subject to the new 25% “Trump Tariff,” but they are still proving to be cost effective. Note that to use these sensors, the Mayfly needs a “wing” to boost power and translate modbus communication. The most current documentation is here: https://github.com/EnviroDIY/SensorModbusMaster/tree/master/hardware/Modbus-Mayfly_WingShield (with a little extra background and links here: https://github.com/EnviroDIY/SensorModbusMaster/tree/master/hardware).

      Yosemitech is a small company and has been good to work with. They make sensors when you order/pay, so the turn-around time, with shipping and the inevitable hang up in US customs, takes ~2 months to receive sensors. We are trying to work with them on how they declare and describe the sensors to smooth the ride through customs. The purchasing process is a little tricky because they don’t take credit cards (we usually wire transfer). They also have a warranty/maintenance situation that we basically cannot maintain by purchasing them for use in the US (last I checked).

      The process is involved, so I’m all ears for alternatives, and will be watching this thread.

      Hi Beth,

      Thanks for your detailed answer !
      We contact YOSEMITECH, and we will try that the fast delivery time.
      Also, we found similar equipment in Isweek (www.isweek.com). They are only dedicated to sales

      Thank you for your advice, we will take them into consideration when buying the MyFly
      Thanks again !

      CESAR
