In India, people those who rely on septic tank system are facing so many problems. It is necessary to avoid abnormality in septic tank and more importantly the death of manual scavengers due to toxic gas such as hydrogen   sulfide exposure (asphyxiation) which is a byproduct of anaerobic bacteria present inside the septic tank. If the tank is not pumped out at a regular interval then anaerobic bacteria can pass from septic tank to drain field through fluid and cause septic tank failure. Our unique solution can able to overcome the above problems by fixing the toxic gas sensor inside the septic tank system which will collects data at regular intervals and compares its value to the permissible exposure limit (PEL) - value to say as toxic.   10 ppm is the  PEL  (8 hour time-weighted average). 10–20 ppm is the borderline concentration for eye irri tation (credit: Wikipedia) . If the toxic gases are going beyond permissible exposure limit (PEL) then, t...

Solution to reduce crowd in banks Most of the Indian banking sectors have a device (say, token dispenser unit) nearer to the gate as shown in Figure 1. The person who is entering into the bank for any reason should press the button on token dispenser unit to get the token. The person who is receiving the token will have date, time and the token number. Apart from that, there will be a device (say, token display unit) in the top of the bank. The token display unit displays the token number which is in process and the counter number which is processing the token number as shown in Figure 1.The person receives the token from the token dispenser will have to wait until his/her token number is called or displayed in token display unit. If the token number of the person and the token number which is in process have a big difference, then that person has to wait for a long time. To overcome this, we are going to fetch the token number which is in process and upload it in the cloud. From ...
