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...
