SR602 PIR Motion Detection Sensor Features PIR or Passive Infra-Red sensors detect motion based on infrared light of ambient heat. PIR sensors are commonly used in security alarms to detect the presence of human. The SR602 sensor is able to detect movement up to a distance of about 3 meters. This sensor has a digital output. When it detects motion, output will be High and it last 2.5 second. After that it returns to LOW. Note You can adjust sensitivity and HIGH time duration usin...

Heart Rate Pulse Sensor Features Heart Rate Pulse Sensor can be used to measure the heart rate and some related parameters such as cardiac arrhythmia (i.e., abnormal heart rhythm). If you touch this sensor with any area of your skin that is closest to the arteries (such as the finger or earlobe), the sensor detects blood in the arteries. Each time the heart beats, blood is pumped through the arteries, and the sensor detects the flow of blood and increases the output voltage. Note This sensor has an analog o...

SW-520D Vibration Tilt Sensor Features The SW-520 sensor consists of two metal balls which switches as a trigger. When the switch is positioned horizontally, and when the sensor angle is less than 10°, the circuit is open (off state) and more than 10°, it is closed (on stated). But when the switch is positioned vertically, the circuit is open when the sensor angle is less than 45°, and close when the angle is more than 45°. To see exactly how this sensor works, read the datasheet. The SW-520D sensor is ...

OMRON Photoelectric Sensor Features The Omran photoelectric sensor can be used to detect obstacles and objects at 5 to 100 mm distance. There is an LED on the sensor that is always off and turns on when it detect an obstacle. You can also change the LED status using the potentiometer which is on sensor. (That is, the LED is always on and will turn off when the obstacle is detected.) There is another potentiometer on the sensor that can be used to change the sensitivity of the sensor (increase or decrease th...

IR Flame Sensor Analog Output Features This flame sensor module with analog output can be used to detect flames. You can easily connect this module to a variety of microcontrollers and make a device to detect fire. The output is an analog voltage, whose maximum value is 5 volts and will decrease as the flame increases. IR Flame Sensor Analog Output Pinout This Module has 3 pins:OUT: Analog OutputVCC: Module power supply – 5VGND: GroundYou can see the pinout of thi...

SR04 Ultrasonic Sensor Features The SRF04 ultrasonic distance sensor can be used to measure distance with high accuracy. The basic working principle of this sensor is that it produces a high-level signal and sends it to the obstacle. Then the receiver detects the returned wave. The time between the transmission and reception of the signal allows us to calculate the distance to an object. Note When the Trig pin is set High, the sensor generates and sends ultrasonic sound. At that moment the Ech...
