This study examined test piece production and on-the-spot test results of power supply system of road surface temperature sensor module that was put to forecast road freezing at bridge section. The temperature sensor module was produced to replace sensitive sensor (temperature and humidity sensor) of road surface that was put by wire system, and to supply power on-the-spot by itself, And, the study researched optimization considering power consumption for self power generation and sensor operation.
