As the most important part, the work of the sensor is to forward the signals to the valve to turn on the toilet flusher after detecting your body. Its job is to inform the valve when to turn on or off the water when your body comes and leaves. The cover of the sensor is made of plastic ABS or PA and there is an electronic circuit board inside the sensor eye which also includes the led light.

The sensor range for automatic toilet flushers is 400mm-800mm. We can adjust the sensor range and flushing time with a remote controller.

Auto toilet flushers need electricity for sure. Both the sensor and solenoid valve works need electricity power.
Normally three choices:
DC: 4xAA alkaline 6V batteries;
AC: use a transformer to transfer power from 220V/380V to 6V;
DC/AC:Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for 1.5 to 2 years.

Normally there is a manual button on top of the cistern. If the automatic flush and remote control functions fail, you can active the manual button.
