Z1-Mini/MULTISENSOR AIR QUALITY CO2

This configuration will give readings coming from BME280 (temperature, humidity and barometric pressure) and from CO2 sensor SENSEAIR S8; it can be found here. This board will give readings from 0 (clean air) to about 2000ppm of CO2. Resistor on Z1-Mini RX line is used to protect CC2530 since Senseair is a 5V sensor.
