The VOC detectors are read through an 8-to-1 multiplexer on A5. D14 (SDA) and D15 (SCL) control the SSD1306 using I2C. | ||
Most of the sensors are rated only up through 50C. | Most of the sensors are rated only up through 50C. None claim more than 800mW operating power, which is 160mA at 5V. Eight of them together ought thus draw not more than 1.28 amps. | ||
