Mini Cube
The Mini is a quick and easy-to-use prototyping sensor built for rapid deployment and accurate mean radiant temperature (MRT) measurement. A fast, accurate and economical alternative to a globe thermometer, it utilizes 6 medical-grade Melexis thermopile IR sensors to cover nearly the full spherical field of view. A high-accuracy Real-Time-Clock (RTC) and onboard accelerometer track the time and orientation of the scans. The sensor can record data at up 4 times a second, with a fraction of a second settling time. An air temperature and humidity sensor is also included.
Capabilities:
- Mean radiant temperature, ±0.3°C
- Planar radiant asymmetry
- Air temperature, ±0.1°C
- Humidity, ±1.0% RH
The data can be accessed from the sensor in several ways. The primary method is through a .csv file written to a microSD card. For wired applications, the device will broadcast over a serial port at up to 115200 baud. The sensor will also send data over a BLE bluetooth serial port emulation that is readable using the Adafruit Connect Apps for iOS, Android, and desktop Macs, or any other BLE serial emulator. Lastly, the onboard screen can visually display the data for easy observation.
