DTR131 is a contactless microwave motion detector using doppler effect. The electronic device emits a signal which is reflected by moving material. When the material moves, the frequency of the return signal is either high or lower than that of the transmitted signal. If the frequency of the two signals is the same, it is considered that the material does not move. DTR131 the energy of the emitted microwave is 0.15 mw/cm( the angle of the antenna), which is far below the internationally recognized safety indicator 10 mw/cm,DTR certified by FCC-15F. DTR131 can measure the frequency difference between the emitted microwave and the reflected microwave. the change in the microwave energy that can be received (e.g. due to the accumulation of material in front of the antenna) has no effect on the material flow/no material flow detection.
