The 7Semi BME680 Sensor Probe is a precision-engineered, compact environmental sensing solution designed for accurate indoor air quality measurement. Powered by the Bosch Sensortec BME680 sensor, it provides real-time data on temperature, humidity, barometric pressure, and volatile organic compound (VOC) levels using a digital I2C interface. Its 4-in-1 sensing capability ensures comprehensive monitoring in one durable device, ideal for HVAC systems, smart home automation, medical labs, and agricultural settings. With its robust, breathable plastic shell, this probe is engineered to withstand challenging environmental conditions, maintaining performance integrity and long-term reliability.

This sensor probe features a 1-meter 4-wire cable with a Mini Round Shell Plastic connector, simplifying integration into new and existing systems. Operating within a voltage range of 1.71V to 3.6V, it offers excellent energy efficiency. Its construction ensures resistance against dust, particulate matter, and chemical oxidation, safeguarding the internal sensor from environmental degradation. The BME680 gas sensor component is capable of detecting a wide range of VOCs from common indoor sources like cleaning agents, paint, and adhesives—making it indispensable for health-conscious, energy-efficient indoor spaces.

Product FAQ
Q: What is the common use of a Temperature and Humidity, Gas VOC Sensor Sensor?
A: Temperature and Humidity sensors are among the most commonly used environmental sensors. It is widely used to provide the actual humidity condition within air at any given point or in any given place. Such devices are commonly used in situations in which air conditions may be extreme or where air conditions need to be controlled due to varying reasons.

Q: Why is Gas VOC, Temperature and Humidity sensors important in some industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.

Q: How do I choose a suitable Gas VOC, Temperature and Humidity Sensor?
A: There are some important specifications you might need to consider when you choose this product. This includes:
