· the Arduino/code side of things seems to be working fine; ie. the ‘serial monitor’ is showing the activation of the pir sensor when i wave in front, and so too is the led on the relay flicking on/off at the same time. however, the relay is not switching (i don’t hear any click) and so the motor not starting. the connections on the motor side are ok - i have tested by having removing the ...

· /* Sketch for Arduino relay control with PIR sensor PIN_RELAY contains the pin number to which the relay we will control is connected. PIN_PIR contains pin number with connected PIR sensor In the setup function, we set the initial position of the relay (closed). In the body of the loop function, we check the presence of a high level of the signal from the sensor using the digitalRead function. For debugging, the current sensor …
· In this tutorial, we will learn how to use a PIR Motion Sensor with Arduino.. A passive infrared sensor (PIR) is an electronic sensor which is used to detect motion. When a person in the field of the sensor moves, it detects a sudden change in infrared energy and the sensor is …
Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val. Then we use an if and else statement to use this value which we stored to turn on/off the lightbulb ...

· I just need a curtain PIR with a small angle of detection (for distinguish if there is only one person crossing the entrance or maybe two persons enter, one behind the second) we got detect this with a small angle on PIR, no problem And if the curtain PIR has a relay output we can connect it with arduino.
· PIR with Arduino - detects only first motion. The following is an Arduino sketch for 3 PIR sensors. Two PIRs can activate 1 buzzer and show status in an LCD. The third PIR activates a relay. The problem is only the first motion gets detected and the "L" indicator stays on. After that there is …

· Connect the BC547 (pin out - Collector, Base, Emitter) collector to one end of the relay coil. Connect the base to the PIR motion sensor's output signal and the emitter to theGNDd. The other end of the relay's coil is connected to the input voltage (9V). Connect a 1N4001 diode with its cathode on the Vcc and the anode on the emitter of the BC547.

Arduino - PIR Sensor. PIR sensors allow you to sense motion. They are used to detect whether a human has moved in or out of the sensor’s range. They are commonly found in appliances and gadgets used at home or for businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

We interface the IR Motion sensor “OUT” to Pin 4 and the Relay “IN1″ to Pin 8. The light has one of the 120V wire grafted to associate the end associated with the power attachment to the COM(Common) Pin of the Relay module and the one heading off to the light is associated with the NC(Normally Closed) Pin. We utilize a breadboard to interface the VCC and Ground to both modules from our UNO, however, we associate a 1N4007 rectifier Diode to the VCC line of the Relay …
I want to install around 5 PIR sensors attached to 5 Arduino in separate locations. Upon any sensor detecting motion it sends a high signal back to the Arduino that controls the pump via a relay. The question is what module or system would be easiest. Am I right in saying Bluetooth will only connect one module at a time? Really I just need a radio frequency sent out and the main relay station ...
