Thermostat for system testing at low temperatures

Abstract

This bachelor thesis deals with proposal and construction of device that should serve for testing of developed electronic circuits at lower temperatures than the ambient temperature in laboratory. Thermoelectric Peltier’s coolers are used for cooling. The temperature regulation is provided by microcontroller control. The thesis is divided into three parts. First part includes necessary theory for realization of the device. In second part there is the detailed description of construction and function of the device. The third part summarises the measured parameters of the device. The thesis includes the technical documentation
