MQ-3 Alcohol Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. The MQ-3 sensor is one of the MQ series heater-driven gas sensors that has an internal variable resistance from pin A to pin B, which depends on the amount of alcohol in the air. The sensor's output is an analog resistance. This sensor can measure the alcohol concentration in human blood alcohol gas on your breath. Alcohol decreases the i...

MQ-135 Smoke Gas Sensor Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure different kinds of gas combinations. The MQ-135 sensor is a sensor for detecting air quality. This sensor is able to detect smoke, CO2, ammonia, alcohol and benzene in the air. Note After turning on the module, wait for 2 minutes until the inside heater warms up. You can download the datasheet of this module here.[wpdm_package id=...

TSD-10 Thermometrics Turbidity Sensor Features The TSD-10 turbidity sensor measures the turbidity using optics and light passing through the liquid. This sensor has an analog output and requires an ADC converter. It is used in washing machines to measure the density of water turbidity. By using an optical transistor and optical diodes, it measures the amount of light coming from the source of the light to the light receiver, in order to calculate water turbidity. This sensor has a waterproof body. Note You ...

4 Channel Infrared Module Features This module has 4 IR transmitter and receiver pairs that can be used to detect black and white color as well as obstacles. Each channel has digital voltage output. You can adjust the sensor’s sensitivity using the on board potentiometers. Pinout You can see pinout of IR module in the image below. Required Materials Hardware Components Arduino UNO R3 × 1 4 Channel IR Obstacle Avoidance Proximity Module × 1 Male to Male jumper wir...

YwRobot Touch Sensor Module Features Touch Sensor is used to detect human finger touch. It is known as a touch switch as well. These sensors are easy to use and useful in many projects. Before touching the sensor, the output signal is always HIGH. When a human finger touches the sensor, it will generate a LOW level signal. This module also has an LED that lights up when the sensor is touched. Note This module works in trigger mode. That is when the sensor is touched, the digital output is LOW a...

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 ...

MicroDuino Touch Sensor Features This touch button is a simple digital output sensor. It uses the TTP223 chip to detect capacitance change. This sensor features small size, high sensitivity, long power consumption and long lifespan. When the sensor is touched, its output is LOW, otherwise it is HIGH. You can download the datsheet of this module here. [wpdm_package id='19221'] MicroDuino Touch Sensor Pinout This Module has 4 pins: VCC: Module power supply – 3.3 to 5 V GND: Ground OUT: ...

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...
