29/7/2012· Good for 0 humidity readings with 25% accuracy. Good for 40 to 80°C temperature readings ±°C accuracy. No more than Hz sampling rate (once every 2 seconds) Body size x 25mm x 4 pins with " spacing. As you can see, the DHT22 / AM2302 is a little more accurate and good over a slightly larger range.
The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.
