TEMPERATURE & HUMIDITY & ATMOSPHERIC PRESSURE SENSOR
RY-WSY301
INTRODUCTION
RY-WSY301 measure temperature, humidity, atmospheric pressure. It adopts imported high integrated temperature and humidity sensor chip and atmospheric pressure chip. The chip adopts full range calibration digital output. The temperature and humidity sensor chip adopts CMOS ENS technology to ensure high reliability and excellent long-term stability , including a capacitive polymer humidity sensor and temperature sensor made of energy gap material. It is widely used in agriculture, forestry, meteorology and other industries as well as climate room and other places. The sensor can be equipped with ry-nt02 weather light shutter box for outdoor monitoring.
