PIR(Module SB0061) AND ULTRASONIC (HC-SR04) SENSOR ...

· PIR (Module SB0061) AND ULTRASONIC (HC-SR04) SENSOR COMBINATION. Hi friends, I have been doing a simple DIY project with these two sensors separately with my INFIDUINO UNO (Arduino uno R3_full_kit) my pir sensor (INPUT) , LCD 1602,Leds and Buzzer (OUTPUT) have found it working 100% perfect. (and what I wanted is 100% done.)

CSE 423 (MHK-203): PIR and Ultrasonic Sensor

· Both Passive infrared sensor (PIR) sensor and Ultrasonic sensor are used in different purposes. PIR: we can use PIR sensor in different purposes. Like, 1. Human presence detection. 2. Animal presence. 3. Securing area from disposal things. 4. Turn on/off Fan 5. Turn on/off Light. 6. Turn on/off Water Tank. 7. Turn on/off Switches.

Ultrasonic and Passive Infrared Sensor Integration for ...

Ultrasonic sensors do not have gaps in the coverage zone like a PIR sensor and can be sensitive to slight motions at nearly twice the distance. The overall detection range is comparable to that of a PIR sensor. The ultrasonic sensor also can detect motion behind partial obstructions. One of the key advantages of the ultrasonic sensor is the ability to calculate distance to the object in motion.

Interface an Ultrasonic Sensor - Arduino Project Hub

If you completed the previous project, "PIR Sensor Integration", remove the PIR sensor and insert the Ultrasonic sensor. You should have the 4-pin R/A female header soldered to Modulus and there should also be a 4-pin single-row male header soldered adjacently to the R/A female header. This is used so we can wire-wrap 30 AWG wire to the pins. You have to create a solder bridge between each ...

What’s the Difference Between PIR, Ultrasonic, Microwave ...

· Ultrasonic sensors, meanwhile, are highly suitable for spaces in which a line of sight is not possible, such as partitioned spaces, and in spaces requiring a higher level of sensitivity. Examples of such spaces include restrooms, open offices, enclosed hallways and stairways. An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance ...

Ultrasonic Sensor & PIR - Project Guidance - Arduino Forum

· Hi, I am working on a project where when the PIR detects movement and the ultrasonic sensor reads below a given value it triggers a relay and a media player off a digital output pin. If during the playing of the video the PIR sensor detects no movement it stops the video and releases the relay Currently I have this in a loop by which if the value of the PIR is equal to 1023 and the ultrasonic ...

Occupancy Sensors: Passive Infrared, Ultrasonic and Dual ...

· PIR sensors require a direct line of sight between the sensor and occupants in a space. Because of this requirement, managers can strictly define the sensor’s coverage. Ultrasonic sensors cover the entire space and do not need a line of sight. As a result, they can detect people behind obstacles. They also are more sensitive to minor motions, such as hand movements.
