KY-031 Knock Module Features This module is a spring-based sensor that sends a HIGH signal when a vibration is detected. It can be widely used in security systems, or monitoring. You can easily use it with the Arduino board or any other microcontroller. Tip It is recommended to use microcontroller interrupt pins in order to increase accuracy. You can download the datasheet of this module here. [wpdm_package id='17426'] KY-031 Knock Module Pinout This sensor has 3 pins:  VIN: Module power...

US-100 Distance Sensor Features The US-100 is an ultrasonic transmitter and receiver module used to measure distance. The sensor operation is very simple. You only need to measure the return time of ultrasonic waves in order to measure the distance. Then you can divide this time by 2 and multiplied by the sound speed. The sensor measuring range is about 2 to 450 cm. Note The US-100 module has 2 different communication protocol. Method 1: use serial communication Method 2: use Trigger and Echo (similar to ...

RCWL-0516 Microwave Radar Sensor Features The RCWL-0516 microwave radar motion detection sensor is used to detect motion at a maximum distance of 9 meters. The viewing angle of this module is about 270 degrees and it has a digital output. You can install a photocell sensor on this module. Note The RCWL-0516 module does not work properly at a distance less than 20 cm. Note This module can measure a maximum distance of 7 meters by default; but you can adjust distance by placing a resistor behind the board. No...

GP2Y1010AU0F Dust Module Features The GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems. You can download the datasheet of this module here.[wpdm_package id='18191'] ...

MQ-2 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is necessary. Gas sensor is an indoor module and is used at room temperature. The MQ-2 sensor is suitable for the detection of butane, methane, alcoholic, LPG and smoke. It is also sensitive to ignition and combustion of gases. Note Afte...

GML692 Load Cell Sensor Features Load cells are electronic sensors used to measure weight and force. The structure of a load cell is made of an alloy body and a number of tensile strengths that change value by applying force and return to their original value by removing force. The capacity of a load cell is the maximum amount of force it can withstand. Note To measure tensile strength changes, we use the HX711 module. It is a high-precision analog-to-digital converter. Note 2 If you w...

YF-S201C Water Flow Sensor Features YF-S201C is a sensor used to measure the water flow. This water flow sensor mainly consists of a plastic valve body, rotor assembly, and hall effect sensor. This module works based on the hall magnetic effect. So when water flows through the rotor assembly, the rotor will rotate and the hall effect sensor will produce an electric pulse. By counting these generated pulses, the amount of water passing through the sensor can be calculated.The measuring range of water fl...

SW-520D Tilt Sensor Module Featurs A SW-520D Tilt Sensor is an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a metallic ball inside it which moves and makes the circuit. The sensor's sensitivity is at 10 degrees tilt. This module has two output pins for each path. When tilt angle is more than 10 degree, the output is low. Note The output is on trigger mode. You can download the datasheet of this module ...

HTTM Series Capacitive Touch Sensor Features This touch module is available in different series with a variety of backlight colors. It features low price, high efficiency and long lifespan. The sensor part can also be placed on glass and thin plastic.Its output is on trigger mode which works like a switch. That is, when it is touched, its will be HIGH and remains HIGH until the next touch.The input voltage is 2.7 to 6 V and output pin voltage is 3.3 V. You can download t...

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...
