how to develop a sensor based system which helps authorities know if in case toilet, corridor are dirty and need attention
Answers
Explanation:
Then the CR4 sensor can spot the presence of dirt. If it is
present, it can blink the red light. If it is clean, it can
blink the blue light. It assistances to understand the
responsibilities of sweeper by his/her own. If Sweeper is
not clean the toilets for period of time, his/her absence in
cleaning the toilet also reported to the dependable
organization. These all the details are stored in the
database.
2.2.7 SONIC SENSOR
The Sonic Sensor is used for computing the depth. Here
it is used to measure the depth of the septic tank. The
Sonic Sensor is fixed into the Septic tank. Then the
Septic tank get filled means, it can sends the
communications to particular organization. Then they
will allot persons to clean the septic tank. Then septic
tank cleaners will clean the tank. After cleaning it, the
sensor can detect the level, and send messages to
consistent organization.

This ultrasonic sensor can be used for measuring
distance, object sensor, motion sensors etc. High
sensitive module can be used with microcontroller to
integrate with motion circuits to measure the distance,
position & motion sensitive products.
In a nutshell, water depth sensing is using a sensor to
measure the depth of water in a tank or container.
Although various sensors can be used for this
application, we will talk about ultrasonic sensor
application.
With ultrasonic sensors, we can find the water depth
calculation by finding the distance between the
transceiver and the surface of the water. The sensor will
transmit a short ultrasonic pulse, and we can measure the
travel time of that pulse to the liquid and back. We can
then subtract that distance from the total depth of the
tank to determine the water depth.

2.3.1 GSM
GSM stands for Global System for Mobile
communication. It establishes the mobile communication
from one place to another place.
Figure 10: GSM Module
It transfers the information from main circuit to operator.
It uses Time Division Multiple Access (TDMA).
GSM is mainly used for communicating and transferring
message from one person to concerned organisation.
GSM module is used to establish communication
between a computer and a GSM and GPRS system.
Here we are using GSM LT-2 communication module
makes it possible to use GSM paths to provide
monitoring and messaging functions in alarm systems. It
facilitates cooperation with SATEL and third party
control panel diallers or correctly configured outputs.

Answer:
Capacitive touch screens use a layer of capacitive material to hold an electrical charge; touching the screen changes the amount of charge at a specific point of contact.
