Nghe An primary school teacher successfully created an automatic hand sanitizer machine
(Baonghean.vn) - A group of teachers at Nghia Dong 2 Primary School, Tan Ky district, has just successfully manufactured 10 automatic hand sanitizer machines to serve teachers and students.
This is a compact machine consisting of a control circuit and sensor system, a disinfectant spray system, a solution tank, a device housing and a stand. In addition, the group also produces a disinfectant solution consisting of 90-degree alcohol, vitamin E, lemongrass essential oil and Glycerin to kill bacteria and ensure safety for users.

These sanitizers operate on a fully automatic mechanism. When the user puts their hand near the device, the sensor will control the relay to turn on the solution spray system. When the hand is removed, the relay will turn off the spray system. This helps the user not to touch the machine, reducing the risk of cross-infection. Depending on the design size, the solution tank has a volume ranging from 3 - 5 liters.
