Model No : BT31M2
The sensor is an active motion detector, it emits high-frequency electro-magnetic wave ( 5.8GHz ) and receives their echo. The sensor detects the change in echo from even the slightest movement in its detection zone. A microprocessor then triggers the “switch light ON” command. Detection is possible through doors, panes of glass or thin walls.
The microwave sensors is according to the microwave doppler effect , it can be widely used in as automatic control switch, the security system, and Automatic video control system of ATM, as well as other automatic induction control area.
he Detection way has the below advantages compared with other as follows:
1. Non-contact Detection,
2. Suitable for bad environment, immune to temperature, humidity, noise, air, dust, Light^
3. RF interference ability,
4. Transmission power only 0.2 mW, It will not harm the human Body. Simple installation+ easy wiring.
We use appropriative micro processing integrator, not Only for high sensitivity and wide range of detection, and on very reliable work, error rate is Extremely low, It can stable working on the temperature range: – 15 ~ + 70 Celsius degrees.
Important: persons or objects moving towards the sensor are detected best!
NOTE: the high-frequency output of this sensor is < 10Mw- that is just one 100th of the transmission power of a mobile phone or the output of a microwave oven.
