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.

Temp and humidity

DHT11, DHT22/AM2302, and DHT20/AHT20 sensors solve the same broad job, but only some are acceptable substitutes in the same circuit.

Environment sensors

Choose between temperature-only, temperature/humidity, pressure and indoor air-quality modules without treating every environmental sensor as a drop-in substitute.

Light and colour

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