Make science activities more accessible than ever with the Submersible Audio Light Sensor (SALS). SALS comprises a 10-inch black plastic-covered glass tube and a small box attached at one end. The tip of the glass probe (opposite to the small box) is not covered with plastic and detects light. The small box converts detected light to an audible tone and transmits this signal to an iOS or Android app via Bluetooth®. The SALS app can be downloaded to an iPhone®, iPad®, Android phone, and the MATT Connect.
Like many other light detecting devices, SALS can be used in the air to detect differences between light and dark-colored objects. What makes SALS unique is that its probe can also be used in liquids. The device will alert the user to a change in an experimental feature, such as the formation of a precipitate in a test tube, which would decrease light within.
