The MT8870 DTMF module uses the Dual Tone Multi-Frequency (DTMF) decoding technique to convert the analog signals from our mobile keypad into a digital signal. Basically the module converts the keypad audio tone that is generated by mobile phone into a digital signal that can be understood by a  microcontroller like Arduino. 

The module should be powered using +5V and the audio input has to be given from a mobile audio jack to the screw terminals. The digital output can be obtained from the male header pins. The module is commonly used to control applications remotely using a mobile phone, like in home automation or mobile robot control.
