| 摘 要： | AD590 is taken for tempreature sensor,
amplified circuit is composed of operational amplifier and digital display of temperature
is accomplished by digital voltmeter for long-distance monitoring and controlling
temperature of greenhouse. The equipment is known that the error of monitoring and
controlling temperature is not exceed 1 within 0℃～50℃. Long-distance is realized
in the range of 1000 meter.
