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.

Remote motion sensor with LED bulb

Presenting an ESP-01 and PIR sensor module application.. This is a remote motion sensor application for lighting an LED bulb. The sensor module can be kept at a distance of arround 100 feet or less from the LED module. They will interconnect themselves wirelessly. When operated, any considerable movement before the sensor module will cause the LED module to light up the bulb. The bulb will continue to light up for arround 30 seconds, then automatically goes off. The signal can penetrate a 10 inch wall or the ceiling roof also. The sensor module is to be powered by a 12V 2A adapter and the LED module is to be powered by 220V AC source. The remote sensor module can be kept at a place at the gate of your house and the LED module can be placed inside a room. Contact:Subhra Kanti Mukherjee (+91 9836188732)
