This photo attached is an automatic tap. It doesn't seem to have Infrared sensor. Then, which type of sensor is it... Just wondering :p
In summary, this photo attached is an automatic tap. It doesn't seem to have an infrared sensor. Most likely, it's a passive infrared sensor, meaning it won't be producing any infrared of its own, so you would need to use a remote control or cellphone camera to turn it on.

Why do you say that? See that black window at the bottom of the faucet?Pyrus said:

Because that black thing doesn't seem glass like but has rough plastic like texture...

Use your cellphone to look at the window. You can see near IR with most cellphone cameras...Pyrus said:

Well, except that it probably is a PIR (passive IR sensor), so it won't be putting out any IR of its own.berkeman said:
Maybe wave a cold rod in front of it, versus a hot rod to see if you can tell that it's sensing IR...

Could be that the rough texture is deliberate. Most passive IR sensors have a grid like lens so that the sensitivity of the sensor isn't uniform over it's field of view. This increases the amplitude fluctuations that the sensor receives when there is movement.

Duh, I'm a little slow sometimes...berkeman said:
Just take your IR Remote Control for your TV, and hold it in front of the faucet (but out of the path of the water). Wait for the faucet to shut off if your movement turned it on, and then push a button on the control without moving your hand or the control. If the faucet turns on, it's using a PIR sensor. You can even try backing up a ways to see how far away from it you can get and still operate the faucet with your IR Remote Control.
And just for completeness, you can use your cellphone camera viewer to see the IR transmissions coming out of the Remote Control when you push a button...
1. What type of sensor does this faucet use?
The type of sensor used in a faucet can vary depending on the manufacturer and model. Some common types of sensors used in faucets include infrared sensors, touch sensors, and pressure sensors.
2. How does an infrared sensor faucet work?
An infrared sensor faucet uses an infrared light beam to detect movement in front of the faucet. When an object, such as a hand, interrupts the light beam, the sensor sends a signal to the valve to open the water flow. The faucet will continue to run until the object is removed from the sensor's range.
3. Are touch sensor faucets more hygienic than traditional faucets?
Touch sensor faucets are often considered more hygienic because they eliminate the need to touch the faucet with dirty hands. However, regular cleaning and maintenance of any type of faucet can help prevent the spread of germs and maintain a clean and hygienic environment.
4. Can a pressure sensor faucet save water?
Yes, a pressure sensor faucet can save water by controlling the flow of water based on the amount of pressure applied. This can help prevent excess water from being wasted and can also result in lower water bills.
5. How do I know if my faucet has a sensor?
If your faucet turns on and off automatically without a handle or knob to control the water flow, it likely has a sensor. You can also look for a small, round sensor located near the base of the faucet. If you are unsure, you can refer to the manufacturer's instructions or contact their customer service for clarification.
