M5Stack M5StickC ENV III HAT with SHT30 and QMP6988

M5Stack M5StickC ENV III HAT is a compact environmental sensor HAT built for rapid temperature humidity pressure sensing on the M5StickC series. It combines one digital temperature and humidity device with one pressure device to create a neat module for portable weather monitoring and environmental data logging.

Description

This add-on module combines temperature, humidity, and air-pressure acquisition in a small board that fits naturally into portable sensing projects. The SHT30 temperature humidity sensor handles precise temperature and humidity collection, while the onboard QMP6988 pressure device captures atmospheric pressure changes for richer temperature humidity pressure sensing. That combination makes this environmental sensor HAT a strong choice for compact weather monitoring systems and mobile environmental dashboards.

Features

• The ENV III HAT integrates both the SHT30 temperature humidity sensor and a QMP6988-based pressure stage.
• This environmental sensor HAT supports practical temperature humidity pressure sensing on one compact board.
• Separate I2C addresses for the two sensing devices simplify integration with the M5StickC platform.
• Small dimensions make it easy to use for handheld weather monitoring and portable detection nodes.
• High reliability and long-term stability suit always-on sensing applications.

Specifications

Applications

The module works well in portable weather monitoring, indoor environment checks, storage-area inspection, desktop climate logging, and educational sensor experiments. Because the SHT30 sensing stage and the QMP6988 barometric pressure sensor are already integrated, the board gives us a neat environmental sensor HAT for quick environmental sensing without extra breakout wiring.

Other Content

This compact module is especially useful when we want a minimal add-on for the M5StickC ecosystem instead of a larger external sensor chain. It keeps weather monitoring neat and portable while preserving the value of the SHT30 temperature humidity sensor and the QMP6988 sensing stage. As an environmental sensor HAT, it gives stable temperature humidity pressure sensing in a footprint that is easy to mount, carry, and test.

FAQ

What does this HAT measure?
It provides temperature humidity pressure sensing by combining the SHT30 temperature humidity sensor with the QMP6988 barometric pressure sensor.

Why is M5Stack M5StickC ENV III HAT useful for small builds?
Because this environmental sensor HAT adds compact weather monitoring capability directly to the M5StickC series without extra sensor modules.
