We are looking for developer/s for multiple products. You will be helping us developing from our idea to prototype or even finished product and contact with manufacturor. We are looking at long term cooperation on developing several different products in very broad markets. This is reference project.
Two part system consisting of one master unit and several slaves.
Master unit preferably based on low cost ARM processor and linux kernel. Minimum requirements is Wifi, 7 inch lcd touchscreen interface and USB for upgrades. No other I/O needed. At first stage the master units purpose is to through the touchscreen set and get values from the slaves that connect through Wifi.
Slave units work as thermostats and hygrostats keeping temperatures and humidity at the set values. Every slave is both thermostat and hygrostat. Three sensors connected. Two thermal sensors and one humidity sensor. Board should have 4 relay outputs. 2 for heating, 1 for humidifier and 1 for light. Also on the output side should be a 1-10V output to serve light dimmers. Actual values are reported back to master unit through Wifi.
Consideration needs to be taken on production cost.
All software needed to simulate this circuit needs to be in your facilities and a working simulation needs to be shown before any funds are granted for creating a prototype.
