RY-WSY301 Relative Humidity, Temperature And Barometric Pressure Sensor
WORKING PRINCIPLE:
The sensor adopts the imported SHT11 chip and the imported sensor module ms5540c. The module includes a temperature sensing element, a humidity sensing element, a piezoelectric resistance pressure sensing element and an ADC interface IC. It has a wide range and strong anti-static ability. They are converted into digital Modbus protocol output through the change of environment parameters (see Appendix 1).
