Since there is a signal sensor in the device, you can quickly find what you have lost. If you click on the control panel, then the device must make a sound signal. According to the sound signal, you can quickly find the desired item.

How it Works:
The sensor-analyzers of air and temperature, and a chip are built into this device.

The chip receives data from sensors about environmental parameters: carbon dioxide concentration, air temperature in the purse, bag, pocket.

Next, the chip calculates the usual, average parameters by statistics formulas.

When the item falls out of the bag, the chip fixes a sharp change in parameters and turns on the sound siren. In pockets, bags are usually stuffy, objects do not need fresh air. If the purse is fast in the fresh air, then the chip fixes a fast decrease in the ambient temperature or a decrease in the concentration of carbon dioxide. The owner hears the signal from the purse and checks where the signal comes from. If the purse fell, the owner picks up his purse.

The device should have the control buttons - turned on, off, temperature, and carbon dioxide concentration configuration.

The device should be flat to fit into the purse.
