EnSens: Precise Air Quality Monitoring Module

EnSens is a module that delivers ultra-precise air quality monitoring in homes, workplaces, and outdoor environments. Powered by a Bosch sensor, it ensures exceptional measurement accuracy, while a Nordic Semiconductor communication module enables seamless real-time and long-distance wireless data acquisition.

Comprehensive Air Quality Data Collection

The module effectively collects data on temperature, pressure, and humidity, which are crucial for comfort. It also monitors key air quality indicators that significantly affect human health, including AQI, VOCs, and CO₂.

An Application for Android Smartphones

A smartphone app for quickly accessing data from the module and serving as a foundation for a customized user app.

Ready-to-Use

The EnSens module is ready to use with the pre-installed firmware and our Android app. Simply choose how to power the module, and you will have a fully functional air monitoring solution with minimal setup.

Customizable

For those looking for customization, both the firmware and the Android app are open-source, allowing you to modify them to fit your specific requirements.

Flexible Integration for Custom Solutions

Additionally, the module can serve as the foundation for your own device. You can integrate it into a custom enclosure, embed it in smart home systems or industrial air quality monitoring solutions, or adapt it for your specific applications. Our hardware and software provide a solid starting point for further development.

Key Air Quality Indicators

AQI (Air Quality Index)

A composite index that measures the overall quality of air based on different pollutants. High AQI levels indicate reduced air quality, leading to respiratory problems, fatigue, and increased health risks for sensitive groups.

VOC (Volatile Organic Compounds)

Organic chemicals that evaporate easily at room temperature, often released from paints, furniture, and cleaning products. Exposure can cause eye irritation, headaches, dizziness, and long-term exposure may increase cancer risk.

CO2 (Carbon Dioxide)

A naturally occurring gas produced by respiration, combustion, and industrial processes. Elevated indoor levels reduce cognitive performance, cause drowsiness, and in extreme cases lead to serious health issues.
