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...

VL53L0X Distance Sensor Features The VL53L0X sensor is a laser rangefinder. First, the sensor sends a laser pulse, and the distance from object to the sensor is estimated by measuring the travel time of the laser pulse. Due to the very high speed of light, this sensor is not used in applications less than a millimeter. This module can measure a maximum distance of 2 meters. The operating voltage is 2.8 to 5 volts and it uses the I2C protocol to communicate with the microcontroller. You can down...

E18-D80NK Infrared Obstacle Avoidance Sensor Features The E18-D80NK sensor is used to detect obstacles and objects. This sensor works based on transmitting infrared rays. First, the transmitter sends the rays in a direct path. This ray hits the obstacle and returns to the receiver. There is a potentiometer on this module that can be adjusted to change this detection distance from 3 to 80cm. In fact, with this sensor, the obstacle can be detected, but the distance cannot be calculated directly. There is also...

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

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...

Inductive Proximity Sensor LJ12A3-4-Z/BY Features A proximity sensor is a sensor able to detect the presence of nearby objects. The inductive proximity sensor LJ12A3-4-Z / BY has three pins, two of which are connected to a supply voltage of 6 to 36V. The output pin is PNP and NO (Normally Open). That is, it is normally Low and when it detects an object, it is HIGH. The detection distance is 4 mm and it can only detect metal objects such as copper, aluminum, iron, etc. Note Because the operatio...

APDS-9930 Ambient Light Sensor Features This module consists of ambient light , IR and proximity sensors. The detection distance is up to 100 mm. The APDS-9930 sensor measures the ambient light. This sensor can also detect 0.01 Lux brightness in the dark. It can also be used behind dark glass like a mobile screen. For example, it turns off the touch screen during voice calls when your ear is close to the screen.This sensor can be used to adjust the brightness of mobile backlight and the approp...
