This station combines an MQ-135 and DHT11 to show sensor trends alongside temperature and humidity. The module alone does not produce an official AQI or…
The FSR402 is a force-sensitive resistor whose resistance changes with load. It does not directly measure pressure unless contact area is known, and its…
A DS1307 real-time clock module paired with a small OLED screen turns Arduino into a standalone digital clock that keeps accurate time even when it's…
A standard DHT or LM35 sensor tops out at temperatures your hand could touch — a K-type thermocouple paired with a MAX6675 module reads well past that…
