Need an entire electronic circuit that can detect changes in weight and turn on a relay.

The load can be anywhere between 2 ounces to 16 ounces.

If the weight reduces by 0.5 ounce, a relay switch should be turned on.

Need the complete circuit with proper housing and an adapter that works at 110 V and 240 V.
