  • AN3

    Pin 3 analog voltage distance output, scaled at Vcc/1024 per 5 mm and referenced to GND pin 7, per datasheet.

    Type · analogVoltage · 0 V at power-up; distance voltage depends on Vcc, about 293 mV to 4.885 V for 300 mm to 5000 mm when powered at 5 V
  • RX4

    Pin 4 ranging start/stop input; internally pulled high. Hold low to stop ranging, bring high for 20 us or longer to command a range reading, per datasheet.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
