Sensor for pressure, humidity and temperature ENV III SHT30 + QMP6988 - Unit extension module for M5Stack development modules

Expansion ModuleUnitin the form of an environmental sensor that allows to measure temperature, humidity and atmospheric pressure. It uses embeddedSHT30andQMP6988chips for measurements. QMP6988 chip is characterized by extremely high precision of measurement and low power consumption. It is used in mobile applications where precision and measurement stability are required. ENV III environmental sensor communicates withM5Stackmain module usingI2Cinterface.

• ENV III Pressure, humidity and temperature environmental sensor
• Connection cable with Grove connector

The sensor together with the connection cable for connecting it to the main module is contained in a small plastic container for easy storage.

• SHT30- digital sensor of temperature and humidity, which is characterized mainly by high measurement accuracy and low energy consumption. The temperature measurement range is -40°C to 120°C, with an accuracy of ±0.2°C. The humidity measurement range is from 10% RH to 90% RH with an accuracy of±2%.
• QMP6988- Designed for mobile applications, a precision atmospheric pressure sensor. The measuring range of the QMP6988 sensor is from 300 to 1100 hPa, and its accuracy is±3.9 Pa. The resolution of the result is 0.06 Pa.
