Description

The MT8870 module decodes DTMF signals from an audio source and it is suitable for remote monitoring applications, telephone answering machines and more.

The MT8870 module is a low power device DTMF decoder chip. It is a complete DTMF receiver integrating both the band-split filter and digital decoding functions. This module is suitable for modem interfaces, mobile radios, and other DTMF related applications.


XD-61 MT8870 DTMF Voice / Telephone Decoder Module
This component is ideally suited to adding dual tone multi-frequency (DTMF) decoding to your project. This detection module interprets the incoming tone and produces a coded output that can be connected to all manner of microcontrollers.

DTMF is commonly found in touch tone devices such as a phone. The tone is a combination of two separate sine waves that produce a unique signal that can be transmitted or heard. When the module receives the signal it is able to decode it and produce a binary output that can be used in other devices. The module shows the state of the signal through onboard LEDs.

As an idea, you can connect up a mobile phone via 3.5mm to 3.5mm cable to the module. Dialing into the phone from a second mobile and then using the keypad will produce the tones on the original phone. The tones in the call can then be interpreted by the module, allowing you to control all manner of projects.

The pins are suited to standard sockets with a pin pitch of 2.54mm.
