It is basically a temperature and humidity measure sensing device. It is easily used but it needs a specific time for an operation. Its temperature measuring range is from -40 to +125 degrees Celsius with +-0.5 accuracy. This senor measure moisture content and temperature. This sensor is easily connected with other mic
