How Does Urinal Sensor Work?
A passive infrared sensor identifies when the urinal has been used, by detecting when someone has stood in front of it and moved away, and then activates the flush. This reduces water usage, compared to a sensor that would trigger a continuous flushing action the whole time that a presence is detected.

Regarding this, how does a urinal work?

There is two types of waterless urinal, those specifically manufactured for waterless use and then regular water flushing urinals retrofit to work in a waterless configuration. Both work by neutralising the urine smell and preventing it from backing up into the bowl only allowing it to drain away.

Also Know, how do you flush a toilet with a sensor? You can activate a flush by holding the palm of your hand up to the sensor for a few seconds before taking it away. Or place a piece of toilet paper over the the sensor and remove it once you're finished.

Keeping this in consideration, how does toilet sensor work?

How Things Work: How do automatic flush systems in public toilets work? When a user sits down to use the toilet or stands in front of a urinal, the infrared sensor detects his/her body heat. After the user is finished and walks away, the infrared sensor detects the loss of heat and activates the flush mechanism.

Why do urinals smell?

When we flush with fresh water in urinals, it hydrolyses the urea in urine. Hydrolysis of urea present in human urine generates odor in urinals (Udert et al., 2003a). The enzyme urease hydrolyses urea into ammonia and carbamate.

A urinal takes less space, is simpler, and consumes less water per flush (or even no water at all) than a flush toilet. Large numbers of them are usually installed along a common supply pipe and drain.
