Te transmitacje is te reusable or semi- disposable content that clips onto thee sensor mount. It contens a battery, a mikroprocesor, a radio transmiter, and an antenna. The transmiter powers the sensor, reads the contrict signal, performs initiational signal conditioning, and sends the data to thee display device. Some transmitters are rechargeable and last for separal months to a year, while other are dispoblable and reved with each sensor.

Thee device runs a difficare application that receives the data, applies the calibration algorytthm, and presents the glucose reading along with trend information.
