Abstract
A hidden sensing device and its urinal are disclosed. The hidden sensing device, which is attached on some sanitary installations, comprises a conductivity sensor for detecting urine and a Micro-programmed Control Unit (MCU) for processing signals, wherein said conductivity sensor has electrodes extending into urine. The device further includes a microwave sensor controlled by the MCU to detect human's movements. When the conductivity sensor has detected urine, the MCU will turn on the microwave sensor to detect the human's presence or departure.
Claims24
A hidden sensing device, which is attached on a sanitary installation, comprising:
- a conductivity sensor for detecting urine, which has electrodes extending into said sanitary installation in order to touch urine;
- an MCU for processing signals;
- and
- a microwave sensor controlled by said MCU for detecting human's movements;
- when said conductivity sensor has detected urine, the MCU will turn on said microwave sensor to detect human's presence or departure.
A urinal comprising:
- a hidden sensing device;
- batteries for supplying electricity;
- and
- an electromagnetic valve for controlling flushing;
- wherein said sensing device comprise an MCU for processing signals;
- a microwave sensor controlled by said MCU for detecting human's presence and departure;
- and
- a conductivity sensor for detecting urine;
- electrodes of said conductivity sensor are installed under the liquid level of the siphon of the urinal;
- said microwave sensor is installed on the back of the ceramic parts of the urinal;
- once said conductivity sensor has detected urine, said microwave sensor is turned on by said MCU;
- after having detected the departure of human said microwave sensor informs said MCU to open said electromagnetic valve to flush.
