Air Guardian - 0.96" Display
Overview
The Air Guardian takes modular air quality monitoring to the next level. Powered by the ESP32-C3 Super Mini PRO, this baseboard lets you build the exact environmental sensor you need. We've streamlined the design to support a crisp 0.96" I2C display, making your custom build more compact and power-efficient than ever.
Want to measure Carbon Monoxide and Particulate Matter at the same time? With the addition of a second UART port, you now can. We’ve even upgraded the second serial port to a 5-pin layout, giving you total power control over popular sensors like the PMS5003. Combined with a flexible array of 3.3V and 5V I2C ports, the Air Guardian allows for effortless plug-and-play integration with the industry's best sensors from Sensirion, Winsen, and more. It’s your air, monitored your way.
