Development of Wireless Measurement System of Somatic Informations for Stockbreeding Automatization(I) -Development of Single-Channel Wireless Instrument for Measuring Temperature-

축산자동화를 위한 가축의 생체정보 무선 계측장치의 개발(I) -단일채널 체온 무선 계측장치의 개발-

It is important to measure the somatic informations for stockbreeding automatization. This study was carried out for the development of wireless measurement system of temperature in living animals. New method to measure somatic temperature was developed using the single-channel wireless instrument. This system was constructed by oscillator, temperature sensor, wireless transmitter and receiver circuit, single processing circuit, and microcomputer. Two types of sensor were used and compared to measure the temperature. The thermistor sensor was more sensitive and accurate than platinum resistance sensor, however both sensors were performed efficiently. The single-channel wireless measurement systems developed could measure the somatic temperature successfully and offered a versatile system.
