Smart Trash Can Sensor Application Solution

New smart trash cans usually adopt a combination of advanced microcomputer control chips, modern sensor technology, mechanical transmission parts, wireless Internet of Things technology and other new-generation high-tech technologies and traditional technologies to provide society with a fast, accurate and convenient garbage management system.

In general, smart trash cans can be equipped with infrared sensors, ultrasonic sensors, smoke sensors, temperature and humidity sensors, odor sensors and other sensors to collect trash can data.

Monitoring and management are carried out through wireless technology, and high-energy compressors, blowers, ozone or negative ion technology are used to pre-treat the garbage in the trash can and improve the environment in the box and surrounding environment.

The emergence of modern sensor technology has made trash bins more intelligent and more convenient to manage. The following briefly introduces some performance solutions and related sensor technologies of smart trash bins.

1. Automatic sensing function of smart trash can

Traditional trash cans generally need to be stepped on by hand or foot, but trash cans feel dirty and contain a lot of bacteria, and everyone is reluctant to touch them.

The lid of the smart trash can is opened and closed by the sensor. When you want to throw the trash, you only need to approach the trash can, the lid will automatically open, and it will automatically close again after 3~4 seconds after throwing, you don't need it at all touch this barrel.

It can completely solve the hidden safety hazards and effectively prevent the spread of mosquitoes and bacteria. At present, there are three main induction methods on the market: pyroelectric infrared, infrared to tube, and microwave induction.

2. Smart trash can full detection function

There are trash cans in every corner of the city, but the filling level of each trash can is different. For example, the filling level between the garbage bin pedal and sterilization trash bin is highly different. And it is impossible to deal with them in a timely manner all the time in terms of management.

Smart trash cans generally monitor the amount of trash in the bin through infrared sensors or ultrasonic sensors.

When it is detected that the trash can is almost full, the garbage can be compressed by a high-energy compressor. When the garbage is full again, it will automatically connect to the Internet and send the location to the garbage transfer station, so that people can come to clean the garbage.

3. Smart trash can with fire-proof and explosion-proof and sterilization and disinfection functions

First of all, the environment inside the box is relatively complicated, and there are some flammable substances. Especially in summer, the temperature inside the box is very high, and a little carelessness is prone to the accident of spontaneous combustion of garbage.

The installation of temperature and humidity sensors and smoke sensors in the trash can can effectively prevent fires. When it is detected that the temperature in the trash can is too high, it can be exhausted, humidified and cooled.

When the temperature exceeds a certain set temperature, especially when the smart trash can senses a lot of smoke, the fire extinguishing system can be automatically extinguished, and an alarm will be issued to remind relevant personnel to dispose of the garbage!

For household smart trash cans, the indoor temperature and humidity can be collected through the temperature and humidity sensor, so that people can grasp the changes in indoor comfort at any time, which is also a good thermometer.

Secondly, the internal environment of the trash can is generally harsh and humid, and it is easy to breed various bacteria and germs. The humidity data in the trash can is collected through the humidity sensor.
