Product description
In order to reduce cross-infection, the non-touch automatic hand liquid soap dispenser become more and more popular. How does the hand sanitizer achieve non-touch?
Just installing a IR sensor to get the function. When the hand is placed under the hand sanitizer, a sufficient amount of light emitted by the sensor transmitter will be reflected to the receiver, that is, the infrared light emitted by the infrared emitting tube is reflected by the human hand to the infrared receiving tube.
Features
1) The sensing range is 10~80mm. Of course the range can be customized according to your requirement.
2) The sensing range error is up to 10mm, which is high precision.
3) Fast response.
4) Small size.
5) High reliability
Application
Liquid soap dispenser, gel hand sanitizer, alcohol hand dispenser and other machines that need to sense objects.
Parameter
Recommend Circuit
Install the infrared sensor, then connect it according to the following circuit. The signal terminal will
output a voltage signal consistent with the condition of the object to be controlled.
When the object is close to the sensor, it outputs a high voltage signal; when the object is far away from
the sensor, it outputs a low voltage signal.
