RY-WSY301 Temperature, Humidity, and Pressure Sensor

The RY-WSY301 Three-in-One Sensor for Temperature, Humidity, and Atmospheric Pressure is a professional measurement sensor used for monitoring air temperature, humidity, and atmospheric pressure. The sensor employs imported highly integrated temperature and humidity sensor chips along with a barometric pressure chip, which feature fully calibrated digital output across the entire measurement range.

The product can be optionally equipped with an outdoor protective housing (refer to the RY-NT01 or RY-NT02 type outdoor lightweight radiation shield) for measuring ambient temperature and relative humidity in outdoor environments.

Working Principle:

This air temperature and humidity sensor utilizes the imported SHT11 chip and the imported sensing module MS5540C. This module includes a temperature sensing element, a humidity sensing element, a piezoresistive pressure sensing element, and an ADC interface IC. It features a wide measurement range and strong anti-static capability. These components convert changes in environmental parameters into digital MODBUS protocol output.
