Working Principle

This air temperature and humidity sensor uses imported SHT11 chip and imported sensing module MS5540C. This module includes a temperature sensing element, humidity sensing element, a piezoelectric resistance pressure sensing element and an ADC interface IC, with a wide range, Strong anti-static ability. They are converted to digital MODBUS protocol output through the change of environmental parameters.
