A sensor soap dispenser automatically dispenses a small amount of liquid soap whenever the user touches it. It can also dispense hand sanitizer and lotions. The sensor detects a hand's infrared beam and sends a signal to the pump, which then dispenses the soap. The soap dispenser can be used with both touchless faucets and automatic faucets.

There are two types of sensors. A traditional infrared sensor has an LED and a receiver. The LED emits infrared light, which is reflected off the user's hand and detected by the receiver. However, this type of sensor is susceptible to interference from unpredictable factors, including temperature, moisture, and hand placement. Alternatively, a top sensor uses the time of photons to determine distance.

A sensor soap dispenser should be long-lasting. The battery in one should last for three months or more. In addition, the soap dispenser should be rechargeable. You should also consider the design and functionality of the product. Sensor soap dispensers can be sleek and stylish and blend in with stainless-steel appliances.

The style of the soap dispenser should be attractive and durable. Some types are made of glass or plastic, while others are made of stainless steel. Stainless steel dispensers have a more sleek appearance. Glass dispensers are more durable than stainless steel ones and are also corrosion-resistant. A few models are plastic-steel hybrids.

A sensor soap dispenser is useful in medical settings and other settings where hand washing is necessary. This type of dispenser can help prevent the transmission of disease and conserve soap. In addition, it can indicate whether the user has washed their hands for the correct amount of time. In the operating room, this can help doctors and surgeons sanitize their hands and prevent the transmission of germs.
