Suppose you opened the door and went into the washroom and after that shut the door behind you. As soon as the person leaves the washroom, the system again detects the absence and turns the light off.

because there are 10 outputs of 4017, sometimes due to voltage spike at pin#14 the logic can jump to one of the outputs which are not in use…you can try increasing the 0.1uF value to 0.33uF or any other nearby higher value, this will ensure that at power switch ON the logic sequence starts at pin#3. Be that as it may, since the Pin 4 of CD4017 is associated with the Reset pin, every one of the output will turn out to be LOW and henceforth the relay will turn OFF, which thus switches off the light. <> The following diagram in Figure details the way the circuit is built: The primary component that you need to develop the system is the reed switch.

automatic washroom light switch

Typically it can perform most of the analog operations. endobj With this solution you don’t have to worry to keep check on the washroom light, which we often forget to switch off at times.

In this project, I will tell you the best way to plan and manufacture a straightforward Automatic Washroom Light Switch Circuit, which will consequently turn on lights when you enter the washroom and turns it off when you leave. Pin1 of the LM741 is connected to the clock pin of the counter IC. In the current century, automation is seen to be implemented in almost everything. Via mechanizing this process, there are numerous advantages like, the individual need not think about switching off the light on or at whatever point he/she is utilizing the washroom.

Both the circuits are not working.I am sure with my work. How to build the proposed automatic light circuit for washroom?

When the door of the washroom is opened and closed, the circuit turns switches On the light using a relay. Automatic Washroom Light Switch Circuit Diagram: The operation of the circuit is as follows. Since Pin 2 of CD4017 is associated with relay, the light will be turned ON.

The automatic washroom light circuit is further strategically placed onto the door so that it can come close to the reed switch when the door closes. Carefully make the connections using solder iron. The automatic washroom light circuit is further strategically placed onto the door so that it can come close to the reed switch when the door closes.

Secondly, the relay should not be connected directly to 4017 output, must be done through a transistor driver.

Am I right? The circuit will look like the image below: Go through the following steps to test your circuit. Working of the Automatic Bathroom Light Switch Circuit Connect the circuit as given in the circuit diagram properly. In NO mode, the circuit is always broken unless you send a HIGH signal to the relay through Arduino.

It is now ready to be tested. The non-inverting pin of the op-amp is connected to the emitter of the transistor while the collector is connected to 5V. The input supply voltage for this IC is from 3 to 15V. Will it shot? LM714 operational amplifier is the first most important component that is used in the circuit. picosoft960791302 B.Tech Final Year Projects, ECE/EEE Projects December 28, 2017 2 Minutes.

We have used a human detecting device to check whether human is present in the room and switching operation … endobj $16.99 $ 16. In case of any mistake, try to de-solder the connections and solder them again. So, the next time when the washroom door is opened and closed, the circuit cuts the relay making the light to extinguish. I mainly work with printed circuit boards on proteus to bring life to my inventions. It works in two modes, Normally Open (NO) and Normally Closed (NC). It is designed to perform many mathematical operations like addition, subtraction, multiplication, division, differentiation, etc by making a feedback circuit with the help of a resister or a capacitor. This may lead to power wastage and also the lifetime of the lights may decrease. Take a Veroboard and rub its side with the copper coating with a scraper paper. If any mistake is made while making the connections, try to desolder the connection and solder the connection again properly, but in the end, the connection must be tight.

I tend to make life easier by making circuits and designs to automate things around me. if the relay does not respond, then your IC may be faulty or some other pinout connection error could be there. �M:�.+{�|ni�v�l���C�U-h(�T���W��I�/U�T;�=�0ȩ�J�J�����a䊄)�C���A�i0k�Q&�ڰ8\����=6�еz����9��eA�,�Dn��s�J��(d�͜t��d��5�)[���W��w CD4017 is a CMOS Decade counter IC. What to do? 2 0 obj

Again when the washroom door is closed, this enable triggering of the decade counter of IC 4017, and thus the relay helps toggling the system in ON and OFF state every time the door is opened or closed. While IC 4017 is designed to handle nine counts, here we have applied only two counts and then reset. >k]���e� }m��?�����L ��#�'��%q�]A}=ct���8����n�\��l֡`���&���J��%`hY3�5&�%#�'8��`xW� 8��<2r�֠�k_SGُ>HJw2g(���Ve��H��]g������K�_��Ҝ��IF7���*� h1��'Bҫ���̟ lAڏ�&�.
