Sensors

This Wiki Page is a summary of different Sensors we have in the lab.

Scope: Measure different environment data and make them available via Statusboard or locally via LCD displays.

Case: sligthly adapted and hot glue fixed version of this Brain: Node MCU v2	Todo: Temporary on top of the workshop for temperatur tests. Later for the yard Calibration needed! Data: Madavi Temp/Humidity/Pressure

Challenges

• the BME280 sensor have a accuracy around +/-1°C. On the small temperatur/huminity sensors (e.g. Charles and Kim): Nevertheless, the ESP2866 is heating quite a lot inside the case. Therefore we needed to move out the sensor of the smaller housing and also added wholes to the 3D printed housing for better ventiliation in general for the micro controller On the dust sensors (Wendy and Luke), the situation is still not perfect.
• callibration was done with infrared thermometer and adjusted in the sensor community software

ToDos & Ideas

• Adjust Temperature Sensors => Done by Phier
• Fix BME280 Lasercutter and Workshop => Done by Milian
• Mount sensors again => Milian
• Send Data to Influx DB => Milian
• Integrate Sensors into new home-assistant setup => Milian & Adrian => open
• add new sensor for Community area (just humidity and temperature) => done
• improve sensors - better measurement result => in progress
• fix dust sensor in laser cube => in progress
• add new outdor dust sensor => in progress

BME-280 provides also humidity and BMP-280 does not have this feature.
