Sensor may allow smartphones to send alerts for rotten food - UPI
A group of scientists is developing a portable, inexpensive and easy-to-use electronic tag to send wireless alerts to smartphones when a telltale gas is emitted by rotten food.
"As we know, spoiled food can be very harmful to our health," said study author Guihua Yu.
"But sometimes we cannot easily notice the slightly degraded food by smell or vision. Therefore, we aim to develop a cost-effective wireless sensor for food spoilage detection with the assistance of mobile phones," he explained.
