Smart doors and windows

The circuit board can collect the relevant data of each sensor to the cloud, and the user can open and close windows through the applet or remote control. The initial estimate of the motor with the battery in the u-shaped slot is 12V 20W.

(1) There are rain sensors, PM2.5 sensors, photosensitive sensors, photovoltaics, and motors.

(2) The rain sensor means that if the window is not closed when it is raining, the window will automatically close. The function of PM2.5 sensor is the same as above.

(4) The photosensitive sensor will automatically close if the window is not closed at night.

(5) Photovoltaic is used to charge the battery of this circuit board.

(6) Be able to judge whether doors and windows are open or closed (this data can be viewed through the applet).

(7) The elderly can also open and close the windows through the remote control at home (because they need to penetrate the wall, they can only use 2.4G mode, not infrared).

(8) There is a rechargeable battery module (within the U-shaped slot of 45MM*45MM*20CM), which needs to drive a 12V 20W motor and supply power to the overall module (wifi, etc.).

(9) Photovoltaic panels, the size requirements are 80CM in length and 50MM in width (directly choose the ready-made in the market, considering that there is only a minimum of 2 hours of care

(10) The motor power is not a rigid requirement and can be changed according to the overall plan.

(11) Mini terminal function: can view the data of each sensor + alarm reminder + remote switch window setting + operation guide and company introduction (single page)

   The gateway control board is connected to the NB module for connecting with the cloud server. The gateway will associate multiple door and window control boards to control multiple door and window switches. There are indicators on the network management, normal state breathing flashes, the pairing market press the button on the gateway while pressing the remote control (long press the indicator does not flash, when the pairing is successful, the indicator becomes the normal state), the detected natural gas alarm light flashes and the bee Buzzer alarm
