Wifi Single Relay Board for Home Automation with Android App

This is a single Relay(normally open) board which has esp8266-12/12E (node MCU) on board and also has 100-230VAC to 5VDC converter on the same board. Can be programmed for Mqtt and it also has nodemcu header which can be used to expand or connect to some i2c device. USB based programming like nodemcu

Smart Input Board: It a board which when connected accross AC loads will sense if the load/switch is on or off, Suited for application where two way switch is used or application like smart bell where the bell is connected parallel to this boards input

Safety Warnings

If you are considering buying this item, you probably already know all this but in the interest of your safety, we feel compelled to state all this clearly. So take a few minutes to read it carefully before buying.

AC mains are very dangerous -- Even a 50 V AC supply is more than enough to kill you. Please Switch off the mains before making or changing connections, be very very careful.If your are not sure of anything related to the Ac supply lines please call an electrician ask him to help you our with it . Do not attempt to interface to mains unless you have adequate training and access to appropriate safety equipment. Never work on high voltages when you are alone by yourself. Always ensure that you have a friend/partner who can see and hear you and who knows how to quickly turn off power in case of an accident. Use a 1A Fuse in series with the input to the board as a safety measure. Basic Wiring diagram is available on our instructables page and github .Please go through it

Fire Hazard: Making wrong connections, drawing more than rated power, contact with water or other conducting material, and other types of misuse/overuse/malfunction can all cause overheating and risk starting a fire. Test your circuit and the environment in which it is deployed thoroughly before leaving it switched on and unsupervised. Always follow all fire safety precautions. From
