· IR proximity sensor detects the presence of a hand and makes the OUT pin LOW. Normally OUT pin keeps HIGH. When it goes low it turns on the PNP transistor and the pump becomes on. I used the BD136 power transistor for the circuit. A 1K resistor is connected between sensor OUT and the base of the transistor. It protects the transistor from burning out.
In most healthcare settings, alcohol-based hand sanitizers are preferable to hand washing with soap and water because it can be easily tolerated and it is also more effective at reducing bacteria. Hand sanitizer is a liquid, gel, or foam generally used to decrease infectious agents on the hands. A sanitizer is designed to kill germs on skin, objects and surfaces. This project aim to design and ...
An infrared (IR) proximity sensor, and a small solenoid is combined here to make the 6-Volt DC powered automatic soap dispenser unit. When the infrared sensor detects the close proximity of a hand, it enables the solenoid driver. The resulting voltage available at the output of the driver energises the solenoid. Solenoids are a great way to induce linear motion for pushing, pulling levers ...
· To adapt the sensor in an automatic hand sanitizer machine, we can yet again implement our work horse IC 555 based monostable, a shown below: The circuit is quite self explanatory, but if you have problems understanding the details, you can always feel free to use the comment box below for initiating a discussion.
· The block diagram of IR based automatic hand sanitiser dispenser is shown in Fig. 1, and its circuit diagram is shown in Fig. 2. It consists of an IR sensor …
The main problem with the IR sensor-based hand sanitizer is that you can’t place them under direct sunlight as the sunlight interferes with the IR sensor. Also, the maximum distance of the IR sensor for detecting the hand is less than 10cm but in an Ultrasonic sensor-based hand sanitizer you can set the distance to more than 10 cm. Before moving to the project, let us first understand what ...
