The objective was to adaptation electronic weight to operating inside vacuum oven firmy Memmert.
To do this:
- data transmission wireless to computer PC (IR transmision);
- power supply from battery;
- temperature measurement;
- save energy mode.
IR communication is used for data transmision wireless to computer PC. IR transmistter is outside electronic weight placed (inside vacuum oven), while IR receiver is outside vacuum oven placed. Additionally, electronic weight has been given temperature sensor. Electronic weight transmits current weight, temeperature and number of measurement to computer PC. Data are storage on computer and save in file. Data are transmitted every 1 or 10 minutes, depending on switch position. Electronic weight is equipment battery power supply and circuit save energy.
