Hardware development, based on ESP8266 Wemos mini (or similar).
- Sensing the temperature of an enclosed space (mini refrigerator)
- Control the temperature of that mini refrigerator from the web, using peltier cells
- Sensing weight (<5 kg)
- Set a gas outlet pressure through a solenoid valve with pressure transducer (range: 0 - 4 bar)
- All the above data should be able to be exported to a web page via wi fi.
Deliverables: source code (for Arduino IDE), sensors specification, wiring diagram.
It is possible to quote the totality of the modules or each module individually. Please send a timeline for each module.
Payments will be made in stages, at the end of each one.
