ELECTRIC RADIATOR FAN DAMAGE ALARM DEVICE

Abstract

This research aimed to 1) design and create the electric radiator fan damage alarm device, 2) determine the effectiveness of electric radiator fan damage alarm device, and 3) evaluate the satisfaction of the users of electric radiator fan damage alarm device.  The research methodology composed of 1) data analysis by surveying the cause of electric radiator fan damage from the workplace of Automobile service, 2) design the circuit of the electric radiator fan damage alarm device, 3) create the electric radiator fan damage alarm device and evaluated the efficiency of device by 5 experts, and 4) implement and test the efficiency of the electric radiator fan damage alarm device and evaluate the satisfaction of the 5 users from the workplaces of automobile services. The data was selected and analyzed by mean.

          The research found that 1) the electric radiator fan damage alarm device composed of 3 main parts; sensor, radiator, and alarm device, 2) the electric radiator fan damage alarm device gained the efficiency at the level of “very good”, and 3) the users of electric radiator fan damage alarm device satisfied the device at “very good” level.
