Infrared Bidirectional Counter with AC bulb

bidirection counter using IR obstacle sensor

This project uses two Infrared (IR) obstacle sensors o notice the direction of movement; if the direction is from left to right otherwise known as the entrance, it will count that the person has moved inside a house. And would keep increasing the number of person moving into the house direction according to this motion, Once the entrance count is above one (1), it will turn on an AC bulb. But if the direction of movement was from ight to left (Exit movement) it will decrement the number of count of people inside the house and will keep decrementing according to this directional motion until the count is zero and it will turn off the AC bulb.

Solar Based Smart Irrigation System with SMS Notification

Solar based smart irriagation system

The design is an automated smart project that has the capacity of detecting the relative humidity, optimum temperature and soil moisture level of a garden or farm using special soil moiture sensors and relay this data to authorized user phone via short message service (SMS). The project design also uses the level of water in the soil to determine when to turn on a DC power pump water into the farm for irrigation purposes automatically. This means it totally eliminates the human labor part in running the successful irrigation in both arid and well rainfall places.

How to build a Smart IoT Hydroponics Monitoring And Control Project Design

This project design was made to monitor and control a hydroponics farm. The scope of the project is to measure pH, TDS value, humidity and air temperature and water temperature of the nutrient solution. The project also automatically pumps water into the base nutrient bucket when the temperature is somewhat high or when the water level guage is saying water level is too low.

How to Design A Power Management System (Smart Fan Project)

PMS (smart fan project)

This project redesigns a standing AC fan to a smart automated version that uses a passive Infrared (PIR) sensor to detect human presence then with the help of an real time clock (RTC) sets two different time modes. Namely, the “Remote Active Mode” and the “Auto Sense Mode”. During the ” Remote Active Mode ” also known as the working hour, the user could the remote control to access the type of speed selection he/she wants. During the Auto Sensing mode the fan controls itself automatically. With the RTC sensor, the fan could tell when it is time for auto mode. And then using the PIR sensor, it could detect human motion and know when there is somebody around needing cool air ventilation. IF the fan senses motion, it would turn itself on and runs on a constant speed which is the speed two but if after some time, it couldn’t detect any motion, it would turn itself off.
