Toxic chemical level measurement

Description

In the kit toxic chemical level measurement physical science quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Sometimes it becomes very difficult to measure the chemical level (depth) directly as the chemicals keep releasing many dangerous gases. To avoid the direct contact of our face with the chemical, we have used a distance sensor, which keeps the update of the depth of the chemical. This level will be displayed on a dot-matrix LCD.

This toxic chemical level measurement kit is used an ultrasonic sensor to measure the distance. The ultrasonic module has two parts: transmitter and receiver. The transmitter sends the USS waves and the receiver receivers these. The controller measures the time between transmission and reception. The speed of the waves is known; hence the level is calculated and displayed on the LCD. The device can be powered with either AC or DC power supply as it has an inbuilt rectifier and filter connected with it.
