This is a thermometer clock module powered with a piece of UM4 (AAA) battery. Its physical size is measured as 58 x 40 mm in width and height. The thickness is 10 mm (battery included).
A set of low voltage detector is built-in in the module. Therefore, when the voltage of installed battery runs under 1.2 volts, full LCD display becomes blinking to warn user to change battery.
It is good to adapt into any end product, which ambient temperature and real time messages are required. Both ℃ and °F version are available. If necessary real time feature can be removed to show temperature only.
In storage, press the lowest key for 4 seconds to turn off LCD for battery power saving.
