remote door bell

This is an ESP-01 and PIR sensor module application. It has a set of two modules, the sensor module and the bell module. The bell module has two parts, the bell module as signal receiver and the ding-dong bell. The sensor module is to be placed at outside of the premises and the door bell module can be installed at a distance around 100 meter away from the sensor. Upon switching, both will interconnect wirelessly. When a motion of a living being is detected before the sensor module, the bell module at a 100 meter distance, will respond with a ding-dong sound. The sensor module is to be powered with a 12V DC, 2A adapter and the bell module is to be powered with a 5V DC, 2A power adapter. The ding-dong bell is to be connected with the bell module in the following way: The live wire of the 220 V AC source should pass through the bell module. The nutral wire from the AC source should go directly to the ding-dong bell, other input of the ding-dong bell should be connected to the AC output from the bell module.
