Sound Sensor Module GSM the DS18B20 can derive power

the DS18B20 can derive power directly from the data line ("parasite power")

AVRdude is available for many platforms

Insulated resistance >10MΩ(500V)

This Integrated Circuit (IC) has four AND gates and each gate has two inputs

Sound Sensor Module GSM the DS18B20 can derive powerThis sound sensor can identify the presence of sound. The sensor sensitivity can be adjusted by potentiometer. The sound sensor module work like that: when the intensity of the sound can not reach set threshold, the OUT pin will output high level 5 volt ( open ). When the intensity of the sound reach more than the set threshold, the OUT pin will output low level (2. 5 volt). supply voltage range: 3. 3V 5. 3V Comparator IC: LM393 Mic type : capacitive
