I need a schematic and PCB for connecting a temperature and humitity sensor over RS485 / RS422 to a central computer. There are 12 sensors in all to go into greenhouses. Once the temperature drops I need to switch on heaters 240V, 10A supplies and there are 2 per greenhouse. Just need a schematic and PCB at this stage with a view to make all 12 and more as phase 2 of the project.

I have a wealth of experience in producing the sort of design to meet this brief. my fee would include a design proposal to act as a specification to ensure that all of your product criteria are met. This seems like a simple project on the face of it, but having worked on dozens of similar projects, I am aware of many if the common pit falls that lead to an unreliable product. I realise that my bid is above your ideal budget, but this accounts for the development of a design which avoids these pitfalls. Please get in touch if you wish to discuss my proposal further. Kind regards, Anna Millington
