POSCO commercializes tennis ball-type smart sensor to detect harmful gas

South Korea's steel group POSCO has developed a waterproof smart ball sensor that can be thrown into an enclosed space such as the interior of an empty fuel tank to instantly detect harmful gases. The tennis ball-sized sensor can communicate with portable devices like tablets.

POSCO has partnered with Handong University and Node Talks, a wireless sensor communication technology company, to develop a ball-shaped gas sensor called Smart Safety Ball.

The ball with a diameter of 60 millimeters (2.3 inches) can detect the saturation level of three types of gases -- oxygen, carbon monoxide, and hydrogen sulfide -- and instantly send results to smartphones or tablet PCs.
