About this product
The 7Semi SHT45 + SGP41 Environmental Sensor Breakout combines temperature, humidity, VOC, and NOx air-quality sensing on one compact board. The SHT45 measures temperature and humidity, while the SGP41 monitors VOC- and NOx-related air-quality changes. Temperature and humidity data can also be used to compensate the gas sensor for more consistent readings.
Note: A solder bridge is provided near the Power LED and is connected by default, allowing the LED to remain ON during operation. For low-power applications, the solder bridge can be removed to disable the Power LED and reduce power consumption.

Features
• Combines the Sensirion SHT45 and SGP41 on a single compact breakout board for complete environmental monitoring.
• Measures temperature and relative humidity with excellent accuracy and long-term stability using the SHT45 sensor.
• Detects volatile organic compounds (VOC) and nitrogen oxides (NOx) to help monitor indoor air quality and pollution levels.
• Uses real-time humidity and temperature compensation to improve gas sensing performance and measurement consistency.
• Communicates through a standard I²C interface, making integration simple with Arduino, ESP32, STM32, Raspberry Pi, RP2040, and other development platforms.
• Includes STEMMA QT / Qwiic compatible connectors for quick plug-and-play prototyping without soldering.
