Ubyte BME690 Temperature, Humidity, Pressure and Gas Sensor Module

The Ubyte BME690 Temperature, Humidity, Pressure and Gas Sensor Module is a compact environmental sensing module built around the Bosch Sensortec BME690. It measures temperature, relative humidity, barometric pressure and gas/VOC changes, making it well-suited for air-quality monitoring, weather stations, IoT devices, smart home products and embedded sensor development. The module is designed for easy integration with 3.3V and 5V microcontroller platforms through its onboard 3.3V regulator and level-shifting circuitry, while also including ESD protection, a power LED, soldered headers and mounting holes for practical prototyping and installation.

Compatible with Ubyte STM32WB55 Eval Board (https://Pricio.in/product/ubyte-stm32wb55-evaluation-board/), Ubyte S32K312 SmartWheels Micro EV3 Board (https://Pricio.in/product/ubyte-s32k312-micro-ev2-nxp-evaluation-board/) and Ubyte S32K144 SmartWheels Micro EV4 Board.
